1. The frequency of the wave is 4 Hz

2. The period of the wave is 0.25 s

3. The wave speed is 0.32 m/s

What is frequency?

This is the number of complete oscillations made in one second. It can be expressed mathematically as:

Frequency (f) = number of oscillation (n) / time (t)

f = n / t

1. How to determine the frequency

  • Number of compression (n) = 80
  • Time (t) = 20 s
  • Frequency (f) =?

f = n / t

f = 80 / 20

f = 4 Hz

Thus, the frequency of the wave is 4 Hz

2. How to determine the period

  • Frequency (f) = 4 Hz
  • Period (T) =?

T = 1 / f

T = 1 / 4

T = 0.25 s

Thus, the period of the wave is 0.25 s

3. How to determine the wave speed

  • Frequency (f) = 4 Hz
  • Wavelength (λ) = 8 cm = 8 / 100 = 0.08 m
  • Wave speed (v) =?

v = λf

v = 4 × 0.08

v = 0.32 m/s

Thus, the wave speed is 0.32 m/s
