This is the high point of a wave.
crest
This happens when waves bounceoff of a surface.
reflection
This is the person with a higher pitch: Mrs. Miller or Mr. Moore
Mrs. Miller
This is how many kinds of electromagnetic waves there are
seven
This is the word used to classify materials that you can see through
transparent
This is what all waves transfer.
energy
This is the distance from one crest of a wave to the next.
wavelength
This happens when waves bend after hitting a medium.
refraction
This is the object that has sound waves with a bigger amplitude: an airhorn or a ticking clock
airhorn
Can electromagnetic waves travel through empty space?
Yes
This is the word used to describe materials that do not allow light to pass through
opaque
This is the size of a wave that results from two similar waves combining.
bigger
This is where the resting position of a wave is located.
halfway between the crest and trough
This happens when a wave passes through a material
transmission
This is the unit used to measure loudness.
Decibels
This is the electromagnetic wave with the highest frequency
gamma rays
This is the word used to describe materials like wax paper or a foggy window.
translucent
This is the term used to describe what happens when the crest of a wave overlaps with the trough of a wave.
destructive interference
This is the difference between a mechanical wave and an electromagnetic wave.
mechanical waves require matter
electromagnetic waves can travel through empty space
This happens when a wave spreads in all directions.
diffraction
This is the cause of any sound wave.
vibration
This is the electromagnetic wave with the longest wavelength
radio waves
This is the kind of mirror found on a school bus.
convex
This is the kind of wave that results from the combination of a transverse wave and a longitudinal wave.
surface wave
This is the kind of wave that travels perpendicular to its source.
transverse
This happens when my sound waves hit your ears.
absorption
Is loudness related to amplitude or frequency of a wave?
amplitude
This is the relationship between wavelength and frequency
indirectly related; one goes up and one goes down
This is the kind of lens that a concave mirror is similar to.
convex
This is what happens to wavelength when frequency is reduced.
it increases
