Question

Calculate wavelength of the sound wave whose frequency is 220 hazard and speed is 440 m second in the given medium

Answer 1

Question : -

Calculate wavelength of the sound wave whose frequency is 220 Hz and speed is 440 m/s in a given medium.

Answer : -

Given that,

Frequency $(\nu)$ = 220 Hz

Speed = 440 m

To find,

Wavelength $(\lambda)$ = ?

We know that,

Wavelength $(\lambda) = \frac{speed}{frequency}$

Wavelength $(\lambda) = \frac{440}{220}$

Wavelength $(\lambda) = \frac{\cancel{400}} {\cancel{220}}$

Wavelength $(\lambda)$ = 2 m

Therefore, the wavelength is 2 m.

➧ Frequency (v) = 220 Hz
➧ Wave Speed (u) = 440 mˢ−1

❱ Wavelength (λ) ➾ u / v
