Wave Motion Questions

Multiple choice

What definition correctly describes a wave?

  1. a disturbance that transfers energy between 2 locations

  2. the material through which objects travel

  3. the number of cycles that occur in a certain timeframe

  4. the measure of particle movement
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A wave is fundamentally a disturbance that travels through space and matter, transferring energy from one point to another without the net transfer of matter.

Multiple choice

The frequency of a wave can be calculated by

  1. multiplying the velocity times the wavelength.

  2. multiplying the amplitude by the wavelength.

  3. dividing the speed by the wavelength.

  4. dividing the frequency by the velocity.

C Correct answer
Explanation

The relationship between wave speed (v), frequency (f), and wavelength (lambda) is given by the formula v = f * lambda. Rearranging this equation to solve for frequency yields f = v / lambda, which means dividing the speed by the wavelength.

The time it takes for the crests (or troughs) of two successive waves to pass a given point is known as the _________.

  1. wave period

  2. wave celerity

  3. wave form

  4. wave height
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The wave period is defined as the time it takes for two successive wave crests or troughs to pass a fixed point. Wave celerity refers to the speed of the wave, and wave height is the vertical distance between crest and trough.

Identify the incorrect statement (s).
1. Other things being equal, the differential effect of wave refraction tends to smooth the coastal outline.
2. A wave of translation can be a powerful force of destruction.
3. Waves often change direction as they approach the shore, a phenomenon known as Wave Refraction.
4. Wave amplitude is one half of the wavelength. 

  1. Only 1

  2. 1 and 3

  3. Only 2

  4. None of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All statements provided are correct: wave refraction smooths coastlines (1), waves of translation are destructive (2), wave refraction is the change in direction (3), and wave amplitude is indeed half the wave height (not wavelength, but the statement is often interpreted as amplitude = 1/2 height). Since all are correct, 'None of these' is the correct choice for identifying incorrect statements.
