Question

A sound wave travels with a speed of 342m/s . If wavelength is 1.5cm, what is the frequency .will it be audible

Answer 1

$\underline\bold\pink{\huge{HELLO\:DEAR}}$

$\underline\bold\red{\huge{ANSWER : }}$

GIVEN,

⭐ Wave velocity = 342 m/s.
⭐ Wavelength = 1.5 cm = 0.015 m.
⭐ Frequency =

$\frac{342}{0.015} \: hertz.$

$= 22800 \: hertz$

⚡ NOW, We know that audible range of sound ranges from 20 Hz to 20,000 Hz. But the frequency obtained is 22800 Hz. So, it is inaudible sound and hence will not be audible.

Answer 2

Wave velocity = 342 m/s. 

Wavelength = 1.5 cm = 0.015 m. 

Frequency = 22800hertz 


NOW, We know that audible range of sound ranges from 20 Hz to 20,000 Hz. But the frequency obtained is 22800 Hz. So, it is inaudible sound and hence will not be audible.
