Waves test CP
waves are repeating disturbances that transfer—- through matter or space
energy
A line perpendicular to a reflecting surface is called the _.
incidence
—- is a type of wave that can travel through empty space
light
A glass prism is able to bend light because
light is refracted as it enters a different medium
Increasing the amplitude if a sound wave will make it
louder
a —- is a solid, liquid, or gas that a wave travels through
medium
what is the matter through which a wave travels through called?
medium
an echo is an example of sound wave
reflection
A pencil in water appears broken due to which wave interaction
refraction
The bending of light waves as they bend around an object is called
refraction
The bending of light waves as they pass through one medium to another is
refraction
A tuning fork stats to vibrate when a certain note is played on the piano. this is an example of—-
resonance
refraction occurs when a wave changes its —— as it passes through a different medium
speed
visible light waves do not diffract as well as radio waves because
the wavelength of the light waves are too small
All electromagnetic waves—-
travel at 300,000,000 m/s
what is the bottom of a wave called
trough
if the angle of reflection is 25 degrees, the angle of incidence is
25 degrees
An example of compressional wave
Sound wave
Which electromagnetic wave comes from the sun to give you vitamin d
Ultraviolet waves
light waves travel the fastest in
a gas
example of what sound waves would have the greatest speed traveling through
a hot pan
Houses with carpet are much quieter than houses with tile or hardwood floors because of sound wave
absorption
Wave A carries more energy than wave B. Wave B has a smaller ____ than wave A.
amplitude
height from a wave to the middle
amplitude
In order for reflection to occur, the wave must —- an object
bounce off
Gamma rays are dangerous because they
break down molecules and cells
Sound waves are
compressional
what is the top of a wave called
crest
