A sound wave enters a new medium where sound travels faster. How does this affect the frequency and wavelength of the sound OA
The frequency increases and the wavelength decreases.
OB.
The frequency decreases and the wavelength increases.
O c.
The frequency stays the same and the wavelength increases.
OD.
The frequency stays the same and the wyelength decreases
.
OE.
Neither the frequency nor the wavelength is affected.

C. The frequency stays the same and the wavelength decreases

Explanation:

The speed of a wave, 'v', is given as follows;

v = Frequency, f × Wavelength, λ

∴ v = f × λ

Therefore, the speed of the wave is directly proportional to the wavelength

v ∝ λ

When the speed of the sound wave increases as it enters a new medium, we have that frequency of the wave, which is determined at the source, remains the same, while the wavelength of the wave increases

As 'v' increases, λ increases

Therefore, for an increase in velocity of the wave, the frequency of the wave stays the same and the wavelength increases.

the plateau is likely to turn into a desert do to corrosion.
