Questions and Answers
  • 1. 

    The number of waves that pass by in a second is known as the wave's

    • A. 

      Wavelength

    • B. 

      Frequency

    • C. 

      Speed

    • D. 

      Amplitude

    Correct Answer
    B. Frequency
    Explanation
    Frequency is the correct answer because it refers to the number of waves that pass by in a second. It is a measure of how many complete cycles of a wave occur in a given time period. Wavelength, on the other hand, is the distance between two corresponding points on a wave, such as the distance between two peaks or two troughs. Speed is the rate at which a wave travels through a medium, while amplitude is the maximum displacement of a wave from its equilibrium position.

    The power of a wave comes from the wave's

    • A. 

      Wavelength

    • B. 

      Frequency

    • C. 

      Speed

    • D. 

      Amplitude

    Correct Answer
    D. Amplitude
    Explanation
    The power of a wave comes from its amplitude. The amplitude of a wave is the maximum displacement of a particle from its equilibrium position. In other words, it represents the intensity or strength of the wave. The larger the amplitude, the more energy the wave carries and the more powerful it is. Therefore, the correct answer is amplitude.

    The distance between two identical points on a adjacent waves is the wave's

    • A. 

      Wavelength

    • B. 

      Frequency

    • C. 

      Speed

    • D. 

      Amplitude

    Correct Answer
    A. Wavelength
    Explanation
    The distance between two identical points on adjacent waves is known as the wavelength. It represents the length of one complete wave cycle and is measured from crest to crest or trough to trough. The wavelength determines the characteristics of the wave, such as its energy and frequency. Therefore, the correct answer is wavelength.

    Factors that affect a wave's speed are:

    • A. 

      Wavelength & energy

    • B. 

      Frequency & amplitude

    • C. 

      Wavelength & frequency

    • D. 

      Amplitude & tension

    Correct Answer
    C. Wavelength & frequency
    Explanation
    The speed of a wave is determined by its wavelength and frequency. Wavelength is the distance between two consecutive points on a wave, while frequency is the number of wave cycles that pass a given point in a second. The relationship between wavelength and frequency is inversely proportional, meaning that as the wavelength increases, the frequency decreases, and vice versa. This relationship affects the speed of the wave, as a longer wavelength with a lower frequency will result in a slower wave speed, while a shorter wavelength with a higher frequency will result in a faster wave speed. Therefore, both wavelength and frequency are factors that affect a wave's speed.

    The material a wave travels through is called the

    • A. 

      Medium

    • B. 

      Amplitude

    • C. 

      Energy field

    • D. 

      Antinode

    Correct Answer
    A. Medium
    Explanation
    The material through which a wave travels is called the medium. This is because waves require a physical substance to propagate through, such as air, water, or solid objects. The medium allows the wave to transfer energy from one point to another. Amplitude refers to the maximum displacement of a wave from its equilibrium position, energy field is not a term commonly used to describe the material a wave travels through, and antinode refers to a point of maximum displacement in a standing wave.

    If the speed of a wave remains constant, what will frequency be if the wavelength is shortened by half?

    • A. 

      Increase

    • B. 

      Double

    • C. 

      Halve

    • D. 

      Decrease

    Correct Answer
    A. Increase
    Explanation
    When the wavelength of a wave is shortened by half, the frequency of the wave will increase. This is because frequency and wavelength are inversely proportional to each other, according to the wave equation v = fλ, where v is the velocity of the wave. Since the speed of the wave remains constant, if the wavelength decreases, the frequency must increase to maintain the same velocity. Therefore, the correct answer is increase.

    By counting the number of crests that pass by a given point in a certain amount of time, a person can calculate the wave's

    • A. 

      Tension

    • B. 

      Speed

    • C. 

      Wavelength

    • D. 

      Frequency

    Correct Answer
    D. Frequency
    Explanation
    By counting the number of crests that pass by a given point in a certain amount of time, a person can determine the frequency of the wave. Frequency refers to the number of complete cycles or oscillations of a wave that occur in a given time period. Therefore, by counting the number of crests passing by, one can calculate the frequency of the wave.

    The wavelength is represented by which letter?

    • A. 

      A

    • B. 

      B

    • C. 

      C

    • D. 

      D

    Correct Answer
    A. A
    Explanation
    The correct answer is A. In physics, the wavelength is represented by the Greek letter lambda (λ). It is a measure of the distance between two consecutive points on a wave that are in phase with each other. The wavelength determines the color of light in the electromagnetic spectrum and is inversely proportional to the frequency of the wave.

    The wave trough is represented by which letter?

    • A. 

      A

    • B. 

      B

    • C. 

      C

    • D. 

      D

    Correct Answer
    D. D
    Explanation
    The wave trough is represented by the letter D. In a wave, the trough is the lowest point or the bottommost part of the wave. It is the point where the displacement of the wave is at its minimum or negative maximum. In the given options, letter D is the only one that represents a downward curve, indicating the lowest point of the wave.
