200
What is the bending of a light wave as it passes from one medium into a different medium?
refraction
200

What energy is caused by the movement of electrically charged particles?
Electrical Energy
300
How could electrical energy be transferred to sound energy
Alarm
300
What determines how loud or soft a sound is?
amplitude
300
This happens when light rays bounces off a surface
reflection
300
When the visible light spectrum is combined what color is it?

Light energy
400
Anything moving has this kind of energy
kinetic
400
What determines the pitch of a sound?
the frequency of the wave
400
The most important light source
The Sun
400
As you move from red to blue on the visible light spectrum.
wavelength decreases and frequency increases
500
When an object is in motion, it releases?
Potential
500
A raised object as this kind of energy
Gravitational potential energy
500
What causes sound waves?
vibrations
500
Long ago humans discovered their own light
Fire

What is the difference between refraction and reflection?
In refraction the light bends when passing a new medium, with reflection the light bounces off a surface.
