Wave Motion p.14

Waves have 3 general options when they encounter a medium Reflect Absorb Transmit

Reflect: Bounce back Example: Echoes in a canyon

Transmit: Pass through Example: Sound through air

Absorb: taken in Example: Sound proofing a room

Many times more than one thing is happening at once. Example- Echolocation is the use of sound waves and echoes to determine where objects are in space

Light examples

Reflection of light by the moon works the same as a mirror

Transmission of light through a window

Some mediums bend the light as they pass through Refraction-bending of a wave

We see the color black because it absorbs all light waves

Many times more than one thing is happening at once. Why do we see different colors from white light?

How do rainbows work?

Sometimes the wave gets bent and spread out Diffraction: The bending and spreading of a wave usually around an obstacle
