On a transverse wave, what do we call the point where the medium is displaced the most upwards?

  1. A trough
  2. A node
  3. A pulse
  4. A crest
Show answer and solution

Correct answer: D. A crest

1. A transverse wave rises above and dips below the rest position as it travels. 2. The highest point, where the displacement of the medium is at a maximum, is a crest. 3. The lowest point, where the displacement is at a minimum, is the trough instead. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 8: Transverse waves_

Which distance defines the wavelength of a wave?

  1. Between adjacent points in phase
  2. Between a crest and the next trough
  3. Between a crest and the rest line
  4. Between the start and end of a wave
Show answer and solution

Correct answer: A. Between adjacent points in phase

1. Two points are in phase when they are separated by a whole number of complete wave cycles. 2. The wavelength is the distance between any two adjacent points that are in phase. 3. Crest to crest and trough to trough are both examples of this same distance. 4. The distance from a crest down to the rest line is the amplitude, which is a different quantity. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 8: Transverse waves_

What exactly does the frequency of a wave count?

  1. Metres between two nearby crests
  2. Crests passing a point each second
  3. Seconds between two nearby crests
  4. Metres a crest moves each second
Show answer and solution

Correct answer: B. Crests passing a point each second

1. Stand at one place beside a pond and start a stopwatch as a crest goes past. 2. Count the crests that pass you in one second, and that count is the frequency. 3. The frequency is measured in hertz, which means events per second. 4. The time between two successive crests is the period, and the gap in metres between them is the wavelength. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 8: Transverse waves_
