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.
Refraction and what both involve the bending of waves?
Waves change direction through refraction, and through reflection.
Why do waves change direction when they are near shore?
The reason they change direction near shore is because the density of objects increase!
Why do waves change direction when they travel between one material and another?
Because they are changing mediums.
transverse waves?
this is the waves of secondary waves that has perpendicular to the direction of waves
How does a change in speed cause a change in direction?
newton's

What is the passage of an EM wave through a medium?
when EM waves encounter a material medium, they can interact with it in much the same way that mechanical waves do. A mechanical wave transfer energy in two ways. As it travels, the wave moves potential energy from one place to another.
Why do seismic waves change speed?
"True, the Seismic Waves change speed and direction when they encounter different materials."
What happens when there is reflection in light waves?
That means that the light waves rebound, and change direction.
Refraction and what both involve the bending of waves?
Waves change direction through refraction, and through reflection.
How would compare and contrast the reflection refraction and diffraction of water waves and sound waves?
they are all related to how waves change direction
What are three ways waves change direction?
Reflection, Refraction, Diffraction
Is it true that waves change direction as they approach Shore because of drag?
No
What is the change in direction of waves when the waves travel from air to glass?
The waves are refracted towards the normal (ie towards the line perpendicular to the surface).
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.
What change speed and direction depending on the density and materiel they travel through?
Waves.
