Waves
A wave that moves in a back and forth direction
longitudinal waves
Frequency
the number of waves that pass a fixed point in a given amount of time
what is a wave (what it is and what causes it)
A transfer of energy cased by vibrations
Which type of waves require a medium
mechanical waves
What wave moves perpendicular to the medium.
Transverse wave
What is the Doppler effect
The perceived change in frequency when the source of the sound, or the receiver, or both, are moving.
The lowest point in a wave
Trough
Sound waves are what type of wave
Mechanical
Most dangerous type of EM waves
Gamma
Pitch
How high or low a sound is
What is the highest point in a wave
The crest
list the order of what waves travel fastest through
fastest in solids, slower in liquids, slowest in gasses
The least dangerous type of EM wave
Radio waves
resonance
When two things vibrate at the same natural frequency.
The length from one crest to another
Wavelength
How do animals use waves
Echolocation
Which chart contains the chart of what levels of danger for the waves
Electro magnetic spectrum
Constructive and destructive interference
Constructive interference- when 2 waves join together to make a larger amplitude
destructive interference- when 2 waves join together and cancel out
the length from the resting position to the crest
Amplitude
The types of EM waves IN ORDER
Radio, Microwave, infrared, visible light, Uv rays, x-rays, gamma rays
