Question 1:

What is a wave?

A) A disturbance that transfers matter
B) A disturbance that transfers energy
C) A disturbance that transfers both matter and energy
D) A disturbance that does not transfer matter or energy

Show Answer

Explanation: The correct answer is B) A disturbance that transfers energy. A wave is a disturbance that carries energy through a medium or vacuum without transferring matter. As a wave propagates, it transports energy from one location to another without permanently displacing the particles of the medium through which it travels.

Question 2:

What is the amplitude of a wave?

A) The distance between two consecutive points on the wave
B) The time it takes for one complete wave cycle
C) The maximum displacement of particles from their equilibrium position
D) The number of wave cycles per unit time

Show Answer

Explanation: The correct answer is C) The maximum displacement of particles from their equilibrium position. The amplitude of a wave refers to the maximum displacement of particles in the medium from their equilibrium or rest position. It represents the maximum energy or intensity of the wave and determines the wave's perceived loudness, brightness, or strength.

Question 3:

What is the wavelength of a wave?

A) The distance between two consecutive points on the wave
B) The time it takes for one complete wave cycle
C) The maximum displacement of particles from their equilibrium position
D) The number of wave cycles per unit time

Show Answer

Explanation: The correct answer is A) The distance between two consecutive points on the wave. The wavelength of a wave is the distance between two consecutive points that are in phase, such as two adjacent crests or troughs. It is commonly represented by the symbol λ (lambda) and is measured in meters or other distance units.

Question 4:

What is the frequency of a wave?

A) The distance between two consecutive points on the wave
B) The time it takes for one complete wave cycle
C) The maximum displacement of particles from their equilibrium position
D) The number of wave cycles per unit time

Show Answer

Explanation: The correct answer is D) The number of wave cycles per unit time. The frequency of a wave refers to the number of wave cycles (i.e., complete oscillations) that occur in one second. It is measured in hertz (Hz) and is the reciprocal of the period of the wave, which is the time it takes for one complete wave cycle.

Question 5:

What is the speed of a wave?

A) The distance between two consecutive points on the wave
B) The time it takes for one complete wave cycle
C) The maximum displacement of particles from their equilibrium position
D) The rate at which the wave propagates through the medium

Show Answer

Explanation: The correct answer is D) The rate at which the wave propagates through the medium. The speed of a wave refers to how fast the wave travels through a medium. It is the rate at which the wave energy propagates from one location to another. The speed of a wave depends on the properties of the medium through which it travels, such as its density and elasticity.
