Waves
Transverse waves move in what direction?
perpendicualr
When do standing waves happen?
when two opposing waves combine to result in a single non-moving wave
what are the two types of interference?
Constructive and destructive
The human range for frequency is
20 to 20,000 Hz
Compression waves move in what direction?
parallel
What does reflection do to waves?
waves bounce off and go in a new direction
Polarization effect light waves by
vibrating in one plane only
When does a sonic boom occur?
when a object moves faster than the sound waves it creates
What does the term wavelength mean?
the distance (crest to crest)
What does refraction do to waves?
it bends wave by crossing a boundary between two different media
What has the highest frequency?
gamma rays
Destructive interference is when?
2 waves meet out of phase which the resulting wave is lower
What does the term frequency mean?
the number of cycles per second
the bending of waves around the of a __? (diffraction)
A barrier
what has the lowest frequency
Radio waves
What is the Doppler effect?
the apparent change in pitch due to relative motion
What does the term period mean in waves?
that it takes one cycle
Waves get smaller as they travel through a boundary caused by?
Absorption
What are the five wave behaviors of light
reflection, refraction, diffraction, interference, and polarization
Constructive interference is when
2 waves meet in phase and the resulting wave is higher
