Which property of a wave increases as the wave's energy increases?
a) frequency
b) pitch
c) wavelength
d) amplitude
Which is the lowest point on a transverse wave?
a) amplitude
b) crest
c) wavelength
d) trough
What occurs when the crest of one wave overlaps the trough of another wave?
a) Constructive interference
b) Amplitude shift interference
c) Wave cancellation
d) Destructive interference
Why can't you see your reflection in a brick wall?
a) Reflection of light from a rough surface is regular reflection.
b) No light is reflected from a brick wall.
c) Light rays are reflected in many directions from the uneven surface of a brick wall.
d) Light rays are only reflected in one direction from the rough surface.
Identify the statement that correctly describes the reason sound waves can not travel in outer space
a) Sound waves can not travel in outer space because the gas molecules in outer space are too far apart.
b) Sound waves are electromagnetic, and therefore they are unable to travel in outer space.
c) Sound waves are unable to travel in outer space because they can not travel in medium.
d) Sound waves are compressional, meaning matter in the medium travels back and forth in the same direction the wave travels.
Which term describes the process in which two waves overlap and form a new wave?
a) wave joining
b) interference
c) diffraction
d) refraction
When does reflection occur?
a) when a wave compresses air particles as it travels
b) when a wave bends and changes speeds as it travels
c) when a wave causes ripples in a pool of water
d) when a wave strikes an object and bounces off of it
In which region of a compressional wave are particles far apart?
a) rarefaction
b) crest
c) trough
d) rest position
What is one way sound waves are different from light waves?
a) Sound waves travel through space but light waves can not.
b) Sound waves travel at a slower speed than light waves.
c) Sound waves have shorter wavelengths than light waves.
d) Sound waves are a source of energy but light waves are not.
Which is true about the relationship between light and the electromagnetic spectrum?
a) Visible light travels slower than the rest of the electromagnetic spectrum.
b) Visible light has more energy than the rest of the electromagnetic spectrum.
c) Visible light is the only part of the electromagnetic spectrum that can be detected by the human eye.
d) Visible light is the only part of the electromagnetic spectrum that can travel through space
