Question 1

Which statement best describes the difference between a vibration and a wave?

Accepted Answer

A vibration is a rapid back-and-forth movement of a single object, while a wave is a disturbance traveling outward in all directions from a vibrating source.

Question 2

A stone is thrown into a pond, creating ripples that spread outward. What is being transported by these water waves?

Accepted Answer

Energy, but not matter, is transported by the waves.

Question 3

Which of the following is NOT a mechanical wave?

Accepted Answer

Radio wave

Question 4

Which property of a wave is defined as the maximum displacement from equilibrium?

Accepted Answer

Amplitude

Question 5

A sound wave travels through air. What type of wave is this, and in which direction do the air particles oscillate relative to the direction of wave propagation?

Accepted Answer

Longitudinal wave; particles oscillate parallel to the direction of propagation.

Question 6

Which equation correctly relates the speed $$v of a $$wave to its frequency $$f$$ and wavelength $$\lambda$$?

Accepted Answer

$$v = f \lambda$$

Question 7

A rope is shaken up and down to create a wave. If the period of the wave is $$0.5 s $$and the wavelength is $$2 m$$, what is the speed of the wave?

Accepted Answer

$$2 m/s$$

Question 8

Which of the following statements about electromagnetic waves is correct?

Accepted Answer

Electromagnetic waves are a self-sustaining oscillation of the electromagnetic field and do not require a medium.

Question 9

A wave on a string has a frequency of $$5 Hz $$and a wavelength of $$0.8 m. $$What is its speed?

Accepted Answer

$$4 m/s$$

Question 10

Which of the following best describes the motion of particles in a transverse wave?

Accepted Answer

Particles move perpendicular to the direction of wave propagation.

Question 11

If the frequency of a wave is doubled while its speed remains constant, what happens to its wavelength?

Accepted Answer

The wavelength is halved.

Question 12

Which of the following is a correct unit for wave frequency?

Accepted Answer

Hz

Question 13

A sound wave in air is shown as regions of compression and expansion. What does a region of compression correspond to in terms of air density?

Accepted Answer

A region of higher air density.

Question 14

Which of the following is true about matter waves?

Accepted Answer

Matter waves exhibit both wave and particle behavior.

Question 15

A wave has a period $$T of$$ $$0.25 s. $$What is its frequency $$f$$?

Accepted Answer

$$f = 4 Hz$$

Question 16

Which of the following scenarios best illustrates the concept that waves transport energy but not matter?

Accepted Answer

Water waves pound the shoreline, but the water itself does not travel from the center of the ocean to the shore.

Question 17

Which property of a wave determines how 'strong' or 'loud' a sound wave is perceived?

Accepted Answer

Amplitude

Question 18

A wave pulse is sent down a rope. After the pulse passes, what happens to the particles of the rope?

Accepted Answer

They return to their original position.

Question 19

Which of the following is a correct definition of wave period $$T$$?

Accepted Answer

The time it takes for the wave to repeat itself.

Question 20

A transverse wave on a string has an amplitude of $$0.3 m$$, a wavelength of $$1.2 m$$, and a frequency of $$2 Hz. $$What is the speed of the wave?

Accepted Answer

$$2.4 m/s$$
