ESLet’s ReviewA brief review of information from the unit on Waves
Mrs. Templin8th Grade Physical Science
QUESTION ONE
Transverse
Mechanical
Electromagnetic
Which type of wave does not require a medium?
Great job!
Next question
Oops!
Try Again
A transverse wave causes the particles of the medium to vibrate perpendicular to the direction in which the wave is traveling.
Oops!
Try Again
A mechanical wave requires a medium through which to travel.
QUESTION TWO
Crest
Trough
Amplitude
What is the term for the highest point of a transverse wave?
Excellent!
Next question
Not exactly!
Try Again
The trough is the lowest point of a transverse wave.
Not exactly!
Try Again
The amplitude is the greatest distance that particles in a medium move from their normal position when a wave passes.
QUESTION THREE
Refraction
Diffraction
Interference
Waves bend when they pass through an opening. What is this called?
Way to go!
Next question
Nope!
Try Again
Refraction is the bending of waves as they pass from one medium to another.
Nope!
Try Again
Interference is the combination of two or more waves that exist in the same place at the same time.
QUESTION FOUR
Density of the medium
Temperature of the medium
Both density and temperature of the medium
The speed of sound depends on which of the following?
Perfect!
Next question
Incorrect!
Try Again
The speed of sound does not depend on the density of the medium alone.
Incorrect!
Try Again
The speed of sound does not depend on the temperature of the medium alone.
QUESTION FIVE
Amplitude
Frequency
Wavelength
The energy of a photon is proportional to which characteristic of the corresponding light wave?
Awesome!
Finished
False!
Try Again
The energy of light, when modeled as a photon, is not proportional to the amplitude of the corresponding wave.
False!
Try Again
The energy of light, when modeled as a photon, is not proportional to the wavelength of the corresponding wave.
