Light bends when it passes at an angle into a medium of a different density. When light passes from a less dense medium into a denser medium, like from space into Earth's atmosphere or from air into water, it bends toward the normal, which is an imaginary line perpendicular to the boundary between the two media where the light passes through. Light passing from a denser medium to a less dense medium bends away from the normal.

∙ 14y agoThis is caused by Refraction. When light passes from a less dense medium to a denser medium, its direction is altered causing it to appear bent.

The pebbles lying at the bottom of the clear water of the river appears to be raised up above their actual positionwhy?
Because when light enters a denser medium it is refracted towards normal. The same effect is seen when a straight stick is placed at an angle half into water. The stick appears bent at the point it enters the water. This phenomenon is called 'real and apparent depth', if you are interested.
Does a pencil remain the same when it is dipped in a glass of water?
Physically, the pencil remains a straight pencil. Optically, due to the refraction effect of water, the pencil will appear to be bent.
Why does the straw in the water look broken?
Due to the phenomenon of refraction being caused; straw appears to be bent in water.
Why does a spoon appear bent when immersed in a half filled glass of water?
A pencil in water looks bent because of refraction. when light enters a substance with a different density than the one it came out of, the light either slows down or speeds up. this makes the light appear bent. If there is a pencil in the water, it appears bent because the light is traveling at different speeds through water and air.
A straw placed in a clear glass of water appears to break at the waters surface. Which explains this effect?
Refraction... The change in the density of the medium (from water to air) - causes the straw to appear to be bent.

A stick partly dipped in water appers broken due to?
the phenomenon of refraction. When light travels from one medium (such as air) to another medium with a different optical density (such as water), it changes speed and direction, causing the light rays to bend. This bending of light can make the stick appear broken or bent at the water's surface.

What is the relation of light distance and lenses?
Light travels in a straight line, as long as it is propagating through a constant medium. In space, space is pretty much empty, so the light travels in a straight line. When light passes into a different medium, such as from space into air or from air into glass, the light is bent or "refracted". You can see this for yourself; poke a straight stick into a pond or pool of water. Look at the stick. The light reflected from the stick to your eye allows you to see the stick, but the light from the part of the stick that's in the water is bent - so it appears as if the stick itself is bent. The light from the stick through the water is refracted differently than the light from the stick through the air. The greater the density of the material, the more the light will be refracted. To magnify light, we need to gather in a lot of light and bend it into a smaller area. We can use curved glass surfaces (or curved mirrors) to bend the light into a smaller area, which magnifies the light. The more dense the glass is, the more the light will be bent into a smaller area.
How do you straighten a bent attic stick?
To straighten a bent attic stick, you can apply heat using a heat gun or by soaking the stick in hot water to soften the wood fibers. Then, gently bend the stick back into its original shape, holding it in place until it cools and retains its new shape. Be careful not to apply too much heat to avoid damaging the stick.
Why does a spoon appear bent when immersed in a half filled glass of water?

Why does the sun look little oval at the horizon?
Refraction. It's basically the same reason a pencil put in a glass of water appears to be "bent".
A straw placed in a clear glass of water appears to break at the waters surface. Which explains this effect?
Refraction... The change in the density of the medium (from water to air) - causes the straw to appear to be bent.
Part of a pencil that is placed in a glass of water appears bent in relation to the part of the pencil that extends out of the water What is this phenomenon called?
Caused by refraction. The same effect causes a depth of water to be smaller than it really is.
What could stop the stick in a stick-shift to stop moving?
Bent shift tube or shift fork.
Does the water molecule have a bent or straight shape?
bent
