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 is the change in speed called when light travels through different mediums?
It is simply called a change in speed.
What is change in speed?
Change in speed (more precisely change in velocity) is called acceleration.
What is A change in speed and direction of the wind at different altitudes in the same column of air is called?
wind shear
A change in speed and direction of the wind at different altitudes in the same column of air called?
Wind shear
When speed doesn't change what is it called?
Constant speed
What is does a horizontal line mean on a speed time graph?
It means the speed doesn't change. Stated in different terms, the acceleration is zero.It means the speed doesn't change. Stated in different terms, the acceleration is zero.It means the speed doesn't change. Stated in different terms, the acceleration is zero.It means the speed doesn't change. Stated in different terms, the acceleration is zero.
The rate at which an object changes position is called what?
A change in position in a certain amount of time is called motion.
What is the different between motion and acceleration?
Motion is about speed of location change, acceleration is about speed change.
Why do seismic waves change speed?
"True, the Seismic Waves change speed and direction when they encounter different materials."
What is it called when the velocity doesn't change?
Speed.
What is speed does not change over time called?
A change in speed is a change in velocity - so, a change in speed is an example of acceleration! Acceleration may be positive or negative. Negative acceleration is sometimes called deceleration. When a force acts on an object; it may change the object's acceleration (speed, direction, or both).
The rate of change of displacement is called?
The rate of change of displacement is called a velocity.
