Is this true Light waves do not change speed as they travel from air through water?
Light waves do change speed as they travel from air to water due to the change in the medium's refractive index. In general, light travels slower in water compared to air, causing a change in speed and resulting in the bending of the light waves known as refraction.
Does light waves travel through a diamond air water or a vacuum fastest?
Light waves travel fastest through a vacuum, as there are no particles to interact with and slow down the speed of light. In descending order, light travels fastest in a vacuum, then air, water, and finally, diamond, which has a higher refractive index that slows down the speed of light.
Why does light slow down when it passes from air into water?
Light slows down when passing from air into water because the speed of light is slower in water compared to air due to the difference in the refractive indices of the two mediums. The change in speed occurs because light waves bend as they enter a denser medium, causing a change in direction and speed.
What slows down light?
Light can be slowed down when it passes through a medium such as water, glass, or diamond, due to interactions with the atoms in the material. This causes the light waves to be absorbed and re-emitted, leading to a decrease in speed.
What happens when light waves pass from air into water?
When light waves pass from air into water, the speed of the light waves decreases due to the higher refractive index of water compared to air. This change in speed causes the light waves to bend or change direction, a phenomenon known as refraction. The light waves also partially reflect off the water's surface, which is why you can see a reflection of objects on the water's surface.

How do the light waves coming from the pencil change speeds?
When light waves enter a material like glass or water, they slow down due to interactions with the atoms in the material. This change in speed is related to the optical density of the material, causing the light waves to bend, i.e., refract. Once the light waves exit the material, they resume their original speed in the air.

Why does light slow down in air and water?
Light slows down in air and water because these mediums have a higher refractive index than vacuum. The interaction between light and the atoms or molecules in air and water causes the light to be absorbed and re-emitted, resulting in a slower speed for the light waves.
Does light speed up as it travels through water?
No, light does not speed up in water, it slows down.
How do light waves travel as they enter the water?
As light waves enter water, they slow down due to the change in the medium's density. This change in speed causes the light waves to refract or change direction, bending towards the normal line. The extent of bending depends on the angle of incidence and the difference in the refractive indices of air and water.
What do prisms drops of water and lenses all cause light waves to do?
They all cause light waves to bend or refract, due to the change in medium. This bending is a result of the change in the speed of light as it enters the material at an angle.
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. :)
How are light and sound different?
Different is the speed of propagation. Scroll down to related links and look at "Acoustic or sound waves in air - Radio and light waves in a vacuum".
