Wave Properties and Behavior

What is the lowest point of a wave called?

• Crest

• Compression

• Trough

• Rarefaction

What is the term for the part of a wave where particles are closest together?

• Crest

• Trough

• Compression

• Rarefaction

What is the definition of wavelength?

• The height of a wave from crest to trough

• The distance between one point on a wave and the nearest point just like it

• The time it takes for a wave to pass a point

• The speed of a wave

Which of the following is true about the wavelength in a transverse wave?

• It is the same as the amplitude

• It is the distance from crest to crest

• It is the time for one wave cycle

• It is the speed of the wave

Which part of a wave is referred to as the trough?

• The highest point

• The lowest point

• The midpoint

• The wavelength

What is the effect on the period if the wavelength of a wave is doubled?

• The period is halved

• The period is doubled

• The period remains the same

• The period is quadrupled

In which medium do sound waves usually travel faster?

• Gases

• Liquids and solids

• Vacuum

• Plasma

What is the primary factor affecting the amplitude of a longitudinal wave?

• The color of the wave

• The density of the medium at compressions

• The temperature of the medium

• The length of the wave

What is the effect of a lower amplitude on coil spacing in rarefactions?

• Coils are closer together

• Coils are farther apart

• Coils do not move

• Coils are equally spaced

What happens to the wave when you hold the rope still?

• The wave increases in amplitude

• The wave decreases in amplitude

• The wave stops

• The wave doubles in frequency
