How does the wavelength of a sound affect the way it moves around corners

1 answer:

8 0

This is the diffraction. The longer the wavelength, the wider it spread. (The greater angle of the sector pattern formed)

Answer:

Same frequency, shorter wavelength

Explanation:

The speed of a wave is given by

$v=f\lambda$

$\lambda=\dfrac{v}{f}$

where,

f = Frequency

$\lambda$ = Wavelength

It can be seen that the wavelength is directly proportional to the velocity.

Here the frequency of the sound does not change.

But the velocity of the sound in air is slower.

Hence, the frequency remains same and the wavelength shortens.

Buddy, I think you need to evaluate your question and fix it. Because it's not making any sense, whatsoever.
