Is this true Light waves do not change speed as they travel from air through water?
no. they slow down.
What do prisms drops of water and lenses all cause light waves to do?
Slow down, refracting.
What happens when light waves pass from air into water?
The speed of the light wave slows Some light is reflected off the surface of the water The light that enters the water is "refracted" (the direction of propagation changes due to the different indexes of refraction in air and water) Eventually the water will absorb all the energy of the light if the water is deep enough
Does light speed up or slow down when it leaves water into the air?
The speed of light in air is almost but not quite the same as its speed in vacuum,whereas its speed in water is about 25% less.So when light passes from air into water, its speed drops by about 25% .
How far does light travel in a second?
Light waves move through a vacuum at their maximum speed, 300,000 kilometers per second or 186,000 miles per second. Which makes light the fastest phenomenon in the universe. Light waves slow down when they hit or pass through something.

no. they slow down.
Does light speed up as it travels through water?
No, light does not speed up in water, it slows down.
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".
What happens to the speed of light waves when they travel through a medium?
The speed of light in a material medium is slower than the speed of light in a vacuum. This is a consequence of the electromagnetic wave interacting with the atoms and molecules in the medium, a process merits its own question.Of course, this assumes the medium is transparent for the wavelength of light travelling through it.Light waves slow down when they pass through a medium, eg glass or water
Is the speed of light in water should be more than the speed of light in a vacuum?
No. Light slows down whenever it passes through water. Nothing is faster than the speed of light in a vaccum.
Do water vapor clouds slow the speed of light down?
Yes. Light goes slower in water.
What speed do radio waves travel in air?
Radio waves, microwaves, infrared, visible light, ultra violet, XRays, and gamma rays are all part of the "electromagnetic spectrum". They are all electromagnetic radiation and they all travel at the speed of light (186,000 miles per second). The only difference between them is their frequencies (or wavelengths)
Does the speed of light ever slow down?
The speed of light is different in different substances ... air, water, glass, jello, etc.
What do prisms drops of water and lenses all cause light waves to do?
Slow down, refracting.
Differences between light and sound?
Speed of sound is 343 m/s at 20 degrees Celsius or 68 degrees Fahrenheit. Speed of light is 299792458 m/s in vacuum. Scroll down to related links and look at "Acoustic or sound waves in air and radio and light waves in a vacuum".
