What does spoon look like

According to our ray diagram rules, the reflected lines are parallel and the image is said to form at infinity. Diagram 3 Now we come across a situation in which the image formed is not real; the pencil is moved to within the focal length of the mirror and we find that all three reflected lines diverge rather than meeting at a point of intersection.

The only way for a viewer's brain to make sense of the incoming rays is to assume they originate from a point behind the surface of the mirror - this is represented by the dotted lines, which intersect to form a virtual image since the rays never actually meet, the image is not considered real. It makes sense to interpret diverging rays as light coming from this imaginary point, since they must converge in the opposite direction. You may also notice that the virtual image of the pencil is upright rather than inverted.

As you move a spoon towards your face, there comes a point provided the spoon is big enough that you pass its focal point and your image 'flips' from inverted to upright. Although the pencil is no longer on the same side of the spoon as the focal point, the same principles apply to drawing the ray diagram: rays towards the focal point are reflected parallel to the optic axis and rays parallel to the optic axis are reflected directly away from the focal point as if leaving it.

Clearly these reflected lines do not converge to form a real image, but by extending them beyond the mirror's surface as our brain does automatically we find a point from which it appears the rays originated. An upright, virtual image is formed.

Indeed, the virtual image of our face appears the correct way up when viewed in the back of a spoon. While this isn't a suggestion that you should throw out your bedside mirror in favour of a box of cutlery any time soon, being able to explain such phenomena can be useful. An understanding of the way in which light interacts with non-planar reflecting surfaces like spoons is crucial for scientists making all types of optical equipment, from glasses lenses to space telescopes.

This is the kind of content I enjoy on steemit! These are made from stainless steel with slots or a hole in the bottom of the bowl. This allows you to scoop olives out from their liquid while draining the liquid before placing them in a bowl or on a plate.

They're also used for cherries, garlic, cocktail onions, and other condiments suspended in liquid. A panja is a rice spoon found in India. It features a flat surface and four finger-shaped indentations, found to make it easier to scoop and serve rice. The end of the handle often has a loop to tie off a string for easy storage. You'd think this is like a panja but it's not.

People call them rice paddles, too. They're all based on shamoji, the Japanese rice spoon. It's a large and nearly flat paddle, shaped perfectly stirring vinegar into rice for sushi and serving rice in general. Some have plastic non-stick surfaces, but most are made from bamboo or other types of wood and sealed with lacquer.

Risotto is type of rice, but this is a third type of unique rice spoon. These are made of wood and feature a typical bowl where usually but not always one corner of it comes to a right angle. The bowl has a hole in the middle so when you stir the risotto it can flow through to reduce the amount of grains you're breaking. These are bigger than a tablespoon but the bowl is rounder than oval shaped in order to pick up more food per scoop.

It has a long handle to accommodate serving various types of food, including vegetables and cut up fruit, and to portion out salads. This is more a category of spoon types, since many feature slots.

The slots or holes are designed to allow liquids to drip through while keeping the wet solids on top. Think about serving green beans or cabbage and you've got it. Imagine a ladle that has big tines around the edge of the bowl and you have a spaghetti spoon that aids in picking up soft, cooked spaghetti noodles. In the United Kingdom, they sometimes call it a Yurkle. These often will have a hole in the middle of the bowl to let you measure out servings of dry, straight noodles.

This is another general category for spoons with very long stems and small bowls, aiding in stirring liquid in any sized tumbler. Sometimes called a sugar shell, for some reason this type of cutlery ultimately ended up having a bowl in the shape of a sea shell.

They're about the volume of a teaspoon but with a deeper bowl, meant for serving granulated sugar. They're typically sterling silver and come with formal tea and coffee sets. There are some with flat bowls called sugar shovels, as well. Though these are most commonly used when eating, they serve a purpose for serving and food preparation.

Their volume is three times that of a teaspoon. It's used as a unit of volume, but it's also the most commonly used spoon in general. These are smaller than tablespoons by a factor of three. A teaspoon is now a unit of volume. They're most commonly used as stirring spoons now and sometimes to sip hot coffee or hot cocoa. These are generally larger, with bigger but shallow bowls and long stems. They're coated in lacquer but over time will lose their coating and begin becoming soft and even splintering.

You should toss them out at that point. They are very common in food preparation due to their inexpensive cost but equally good performance. Not all spoons are used in food preparation, cooking, serving, and eating.

There are some used in rituals and special events. I did include a couple food related ones here as well based on their special features. Also called a coronation spoon, these are silver and are used as part of the Crown Jewels of the United Kingdom, which is the regalia first implemented in the 12th century during the coronation of monarchs. These are gifts given during the christening, when a baby is given a Christian name and is baptized.

They are spoons that feature a bust of an apostle at the end of the finial handle. These are typical spoons, just down-scaled to be the proper size for a baby to eat from.

In the present they're often coated in soft plastics and made to be colorful. You'll see them featuring animal heads on the handle or covered in designs from cartoons. This is another religious spoon used by the Eastern Orthodox Church. It's used when serving consecrated wine, often with a piece of the sacramental bread within it.

This is a gross instrument used to scoop out earwax from the ear canal. They aren't used often any more now that cotton swabs are invented and heavily marketed. I hesitate to mention these but for the sake of completion, I will. These are tiny, meant to aid the insufflation of bad stuff. I'm sure you get it. I'd rather not describe it further.

These are a traditional Welsh gift given from a suitor to his promised bride. They're made from wood, carved to be very decorative.

They usually will have two bowls within them, one halfway up the handle. In the carving are symbols for luck, faith, commitment, security, and other positive meanings for a successful marriage. These are another type of religious spoon given as a gift. Popular in the 16th century, they are made from silver and terminate on the handle side with a bust of the Virgin Mary. You may laugh that I included this here but I want people to know they exist.

There's nothing worse that spilling liquid or sauces everywhere and dirtying up a spoon tray, when you can just clip it to the side of the cooking pot instead between stirring. You've heard about not being "born with a silver spoon in my mouth. These days they act as a metaphor, meaning you came from a wealthy family. Who doesn't love these? My mom does and I've spent a fortune on them. These are small spoons that are decorated with locations, words, or symbols from a specific place or event, collected as you travel around the world and displayed in a spoon cabinet.

Speaking of scoops, the ice cream spoons have more rounded, shovel-inspired bowls with long handles but not quite as long as an iced tea spoon. These spoons are used with ice cream, gelato, and shaved ice. Silver baby food spoons are still gifted, but practically speaking, there are some pretty cool options for the littlest mouths these days.
