What does amplitude measure?
a) How tall a wave is and, therefore, how much energy it carries
b) How far apart waves are
c) How often a wave occurs
d) How long it takes one wave to pass
Which wave property measures the distance between waves?
a) Frequency
b) Wavelength
c) Speed
d) Period
What is the Doppler Effect?
a) A change in the frequency of a wave due to some difference in speed between the source and the observer.
b) A change in the amplitude of a wave due to some difference in speed between the source and the observer.
c) A change in the frequency of a wave due to some difference in position between the source and the observer.
d) A change in the amplitude of a wave due to some difference in position between the source and the observer.
A wave travels from left to right, but its particles oscillate up and down. What kind of wave is this?
a) Heat
b) Longitudinal
c) Transverse
d) Gravitational
A wave travels from left to right, and its particles oscillate in the same direction. What type of wave is this?
a) Transverse
b) Electromagnetic
c) Gravitational
d) Longitudinal
What is the major difference between mechanical and electromagnetic waves?
a) Electromagnetic waves need a medium to travel through, but a mechanical wave does not.
b) Electromagnetic waves are transverse and mechanical are longitudinal
c) Electromagnetic waves can travel through a vacuum, but mechanical waves cannot,
