Question

what were the velocity of the way with frequency of 20 and wavelength of 20 mention if the frequency of the sound will be audible here

pls send it soon​

Answer 1

$\sf{\huge{\underline{\red{Given :-}}}}$

• The velocity of a wave with frequency of 20Hz and wavelength of 20m.

$\sf{\huge{\underline{\green{To\:Find :-}}}}$

• The velocity of the wave.

$\sf{\huge{\underline{\pink{Formula\:Used :-}}}}$

• V = λ × μ

$\sf{\huge{\underline{\blue{Solution :-}}}}$

We have,

• Frequency of wave = 20 Hz

• Wavelength = 20 m

Velocity = wavelength × frequency

➝ λ × μ

➝ 20 × 20

➝ 400

Velocity = 400 m/s

The velocity of the wave is 400 m/s.
