What causes light rays to bend when they enter a new medium in a new angle?
when light rays enter a new medium in a new angle it may speed up or speed down
Waves need matter to travel throgh?
waves such as transverse waves, like moving a rope up and down causing waves, does require a medium but energy in the form of light (its still debatible weather its a particle or wave) doesnt need a medium,like electromagnetic waves
For each type of wave compare the vibration of the medium to the direction of the wave?
Transverse waves vibrate up and down. Longitudinal waves vibrate parallel to the medium. Surface waves vibrate in circular motions.
What does light do when it travels through a medium?
Light slows down when going through a medium. This is not to say that the speed of light, c, slows down. It doesn't - c remains constant - rather the light bounces randomly around the medium on its way to its destination, which increases the time it takes for the light to traverse through the medium.
When sound waves interfere to create standing waves the points on the medium that move up and down with the largest amplitudes are called nodes?
false antinodes

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

What causes light rays to bend when they enter a new medium at an angle?
Light rays bend when they enter a new medium at an angle because they either slow down or speed up. They speed up the most if they are in a vacuum.
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. :)
What distinguishes electromagnetic waves from mechanical waves?
electromagnetic waves are wave that do not require a material medium for their propagation while mechanical wave requires a material medium for example light wave is an electromagnetic wave it does not require any material medium(depends on air or water)for their propagation i.e even in the absence of air light will still travel... sound wave is a mechanical wave because sound do not travel in a vacuum....
How does sound react with different phases of matter?
Sound waves have to go through a medium, or matter. Usually the medium is air, but they can go through any matter. Sound waves cannot exist in outer space because there is no matter for the wave to travel through. Sound waves travel at different speeds, depending on the medium. This is similar to light, because light slows down in mediums other than air (eg. water, crystal, ect.)
For each type of wave compare the vibration of the medium to the direction of the wave?
Transverse waves vibrate up and down. Longitudinal waves vibrate parallel to the medium. Surface waves vibrate in circular motions.
How can you change the medium that light travels through?
Anything that light will penetrate is a medium light will travel through. Any such medium will slow light down, to a certain degree. Window glass slows light down somewhat. Water slows light down a bit more. A diamond slows light down greatly (part of the reason for the "fire" in a diamond.)
What is wave in which particles in the medium vibrate in an up an and down motion?
transverse waves
What moves in waves?
The particles of the medium move up and down as the wave passes. The crests and troughs of the waves move with the wave.
What does light do when it travels through a medium?
Light slows down when going through a medium. This is not to say that the speed of light, c, slows down. It doesn't - c remains constant - rather the light bounces randomly around the medium on its way to its destination, which increases the time it takes for the light to traverse through the medium.
