How are Electromagnetic waves different from Mechanical waves?
EM waves have very short wavelengths
EM waves transmit energy instead of matter
EM waves can travel through the vacuum of space (without particles)
EM waves can change direction by reflection
Light waves bouncing off a surface is known as?
Transmission
Refraction
Reflection
Absorption
This is when sound waves reflect or bounce off an an object.
Echo
Transmission
Refraction
Absorption
This is when light changes direction slightly when it passes from one material to another.
Transmission
Reflection
Refraction
Absorption
This describes when the atoms of matter absorb light, and converts the light into thermal energy.
Transmission
Reflection
Refraction
Absorption
When you place things into water they sometimes look bent (see the image below). What is this an example of?
