How will light be refracted if it passes from glass to water?
Bending away from the normal
What happens to to light waves as they pass through water?
if the light rays are coming from air, they will be refracted at the water boundary towards the normal. refraction occurs because the light rays change speed at the boundary as they travel faster in a less dense medium (air) than they do in a more dense medium (water). hope this helps. alert me if it doesn't :)
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.
What is the light ray when it enter or exits a water air at an angle of 15 degrees with the normal?
sometimes bends towards the normal
Will light be refracted more when it goes from air to glass or from air to water?
Gets refracted more in case of glass than water as glass has higher refractive index with respect to air
Why if you equals 0 refractiondoes not takes place?
Because from air to water the item will go towards the normal and in water to air the item will gi away from the normal. So if it is already directly along the normal then it wont be refracted.

Does a rainbow occur because sunlight is selectively absorbed by water in the raindrops or because it is refracted by water in the raindrops?
Rainbows are the result of sunlight being refracted by drops of water in the air.
How is optical density related to refraction?
As you should know, as light travels from one medium into another more optically dense medium (such as from air into water) the light is refracted towards the normal. But why does the light appear to bend and refract? Light acts not only as a particle, but also as a wave. When the light hits the more optically dense medium it slows down. This also happens with water waves. As the waves come towards the shore the ocean becomes more shallow and they speed up, when the water waves speed up they bend away from the normal. The same thing is happening with the light waves. As light waves are hitting the more optically dense material, because they slow down they oppose and opposite effect to the water waves and bend towards the normal. I hope this helped. :)

Why water in a rock pool often appears to be much shallower than it is?
Because the light is refracted and so the water appears shallower than it is Because the light is refracted and so the water appears shallower than it is
Will light be refracted more when it goes from air to glass or from air to water?
Gets refracted more in case of glass than water as glass has higher refractive index with respect to air
Are rainbows a reflection?
Rainbows are caused when light is refracted when entering a drop of water, it is then reflected on the inside of the drop and is refracted again when leaving the drop
Is light refracted more while passing from air to water or water to glass?
yes
Why does the stick appear to be broken?
Light is refracted as it passes through the water.
