Answer:

60 m/s

Explanation:

[tex]v = f \times lamda[/tex]

v = ?

lamda = 0.5 m

f = 120 Hz

v = 120 × 0.5

v = 60 m/s

The speed of the wave at the given wavelength and frequency is 60 m/s.

The given parameters;

  • wavelength of the wave, λ = 0.5 m
  • frequency of the wave, f = 120 Hz

The speed of the wave is calculated by applying general wave equation as shown below;

v = fλ

where;

  • v is the speed of the wave

v = 120 x 0.5

v = 60 m/s

Thus, the speed of the wave at the given wavelength and frequency is 60 m/s.
