WAVES
What is the top of a transverse wave?
Crest
Define reflection.
When a wave bounces off of a surface that it does not go through; waves reflect an equal angle in the opposite direction.
What are the names of the parts of the electromagnetic spectrum?
Gamma-Rays, X-Rays, UV light, Visible light, Infrared, Microwaves, Radio waves
Define frequency.
The amount of waves that pass by in a certain amount of time.
How do transverse waves move?
What is parallel?
What do a Transverse wave and a Longitudinal waves have in common?
Both transfer energy.
Define Scattering.
The phenomenon where light is deflected in various directions after interacting with particles, causing it to deviate from its original straight path.
Why does it look like when solid's are in water it looks like they bent?
What is refraction?
Define amplitude.
The maximum displacement or distance moved by a point on a vibrating body or wave from its equilibrium (or resting) position.
What makes white light?
All the colors of the rainbow combined.
What is a longitudinal wave?
A longitudinal wave is a wave where particles of the medium vibrate parallel to the direction the wave travels.
Define Refraction.
The bending of a wave as the wave passes between 2 substances, causing the speed of the wave to change.
What causes you to feel the heat from a fire?
Infrared
Define pitch.
How high or low the sound is determined by it's frequency.
What color does black reflect?
All the colors
What type of wave is a Light wave?
Transverse wave
Define Absorption.
The transfer of energy to particles of matter; energy from waves is "soaked up" by a substance.
Define decibels.
The unit used to measure the volume of a sound.
Define Visible Light.
Range of wavelengths on the electromagnetic spectrum that can be seen by the human eye (ROYGBIV); the only kind we see.
Define Volume.
How loud the sound is, determined by the amplitude.
