What happens when light goes from water to air?
light rays bend away from normal as it passes from denser water to rarer air
When light is reflected does the direction of the light wave change?
Yes, the light wave goes in the direction of the angle or reflection.
Why does the light bend as it goes through the lens?
Because the lens is curved.
What happens to the direction of light in which it travels during reflection?
it goes in a different direction:>
When do you notice light bending?
Light refracts or bends when it leaves one medium and enters another one (i.e. when it goes from air to water; when it goes from glass to air). This is because the speed of light is different in different materials (light travels in a vacuum at a speed of 3 x 10^8 m/s and is slower in all other mediums). When light slows down (i.e. moves from air into water), the light bends towards the normal; when light speeds up (i.e. moves from water into air), the light bends away from the normal. light is never bent when travelling between media, only refracted. there is research into the bending of light around large objects in space and utilising the bending of electromagnetic waves to create invisible objects.

What direction do water molecules travel when they are heated?
up because when heated, it becomes light and goes up.
Do all transparent objects or substances bend light the same amount?
No. The amount that a particular medium bends light is related to the speed of light within that medium, not its transparency. The medium that light travels through affects the light's speed, and the greater the reduction of speed, the greater the angular distortion. For example, light travels faster through normal air than through glass or water, so when light hits a sheet of glass or a water droplet at an angle, it slows down and changes direction; when it hits the other side of the glass or water droplet and goes back into air it speeds up and changes direction again. if the two sides are perfectly parallel the light travels on in the same direction, but if they are not (as in a prism or a round water droplet), the light can continue on in a different direction. in fact, different wavelengths of light are deflected different amounts by entry into or exit from a given medium, which is what produces spectrums from prisms and rainbows from suspended water droplets. You can test this in a pool, pond, or bathtub: notice how when you look straight down into the water things are not very distorted (though they appear to be a little closer than you'd expect), but when you bend down and look into the water at an angle, objects that are straight look like they have a distinct bend in them.

Is the speed of light in air and in water is the same is the best explanation why the pencil appears broken at the boundary air and water?
If the speed of light were the same in air and water, then the pencil would appearstraight, NOT broken. The beginning of the simplest explanation of why it doesappear broken is the fact that the speed of light is different in air and in water,and that causes light to bend when goes from one into the other.
Why doesn't light bend?
It can be "bent" by passing through a medium of varying density, such as the image of a bent stick placed in a glass of water. This is known as refraction, where the speed of light is slightly lower through water, tricking our eyes into seeing a bent stick. However, in very precise technical terms, light can actually be bent, as it is only radiation. Black holes bend light, which is literally why they are black. The light cannot escape the black holes super strong gravitational pull (If passing by, it may just bent.). The sun for instance, can bend light by 1/1000th of a degree, so tiny that when earth bends light, we may as well say it does not at all. That is why this question asks "Why doesn't light bend?".
What do we call it when we change the direction light is moving?
Reflection: When light is bounced back off a surface in different or same direction Deflection: When light goes through a surface but its direction has changed from before it hit the surface
