Question

If the medium changes, the frequency of the wave remains the same but its speed changes because apart from frequency, the wave speed also depends on:

• A. Frequency
• B. Wavelength
• C. Amplitude
• D. All of them

Answer 1

The correct option is B Wavelength

$v=f\lambda$
As the frequency of the wave remains the same, the wavelength changes with the speed of the wave.
