Electromagnetic waves slow down or change direction?
Electromagnetic waves are produced by the acceleration of an electric charge. Electromagnetic waves have the same speed in a vacuum (or space). They can slow down and change direction.
Is this true Light waves do not change speed as they travel from air through water?
no. they slow down.
Why does the beam of light change direction when it enters the water?
Because it slows down when entering water.
Does light change direction when it is absorbed by a material And if it does then how?
Yes if by absorbed, u mean go through, like water, then yes, it slows down and turns the direction of light
What kind of waves does a light have?
The type of wave of a light wave is a transverse wave, like waves at the beach (surface waves). Transverse simply means that the motion of the wave is perpendicular to the direction of the wave. Simply put, if you're floating on the water, and a wave comes to you, the wave lifts you up, and then you drop back down as the wave passes. You are moving at a right angle to the direction that the wave is moving. This is why surfing is difficult, because you're trying to get it to push you, rather than simply lift you.Sound waves are longitudinal waves; they push particles in the same direction that they are moving in. Pressure waves from explosions are also longitudinal waves.

What is it called when waves change there speed when they go in to different matereals?
This is related to a change in direction. The change in direction is called refraction. The numbers that describe HOW MUCH the speed of the wave slows down is called "index of refraction", especially in the case of light waves.
Why is it When light hits a different surface it will slow down or speed up causing it to change direction?
Because the light travels into a more or less DENSE surface it speeds up or slows down, causing the change of direction
When light reflects off nonmetallic surfaces such as glass water or a road surface the light is polarized The reflected light consists of waves which are vibrating in a direction par?
Polarized light has waves that vibrate only in one direction, or more in one direction than in others. For example, more "up-down" vibrations than "left-right" vibrations or anything in between.

When light enters glass from air it changes direction. What is the change of direction called?
If the light is entering from air or a vacuum, the light will slow down. The affect of this, if the light hits the glass at an angle, is that the direction of the light will change.

How do you demonstrate transverse waves?
Water waves are known as transverse waves because the motion of the water is up and down, or at right angles to the direction in which the waves are traveling. You can see this by observing a cork bobbing up and down on water as the waves pass by; the cork moves very little in a sideways direction.
What s waves move at angles to the direction of movement?
side and up/down
