Question

As the wavelength of a wave in a uniform medium increases, its frequency will provided the velocity of wave remains constant.

• A. decrease
• B. increase
• C. remain the same

Answer 1

The correct option is A decrease

The Wave speed formula which involves wavelength and frequency are given by,

v = f x λ

Where, v = velocity of the wave,
f = frequency of the wave,
λ = wavelength.

If the velocity is constant,then wavelength and frequency are inversely proportional to each other in a uniform medium.
