Question

What will be the wavelength of the sound of speed is 1500m/s and frequency is 95kHz

Answer 1

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

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

⭐ GIVEN, Frequency = 95 kHz = 95000 Hz.
⭐ Wave speed (or, Wave velocity) = 1500 m/s.
⭐ Wavelength =?

We know, Wave velocity = Frequency × Wavelength
=> 1500 = 95000 × Wavelength
=> Wavelength = (1500 ÷ 95000) m.
=> Wavelength = 0.0158 m. (Approx.)

Answer 2

GIVEN, Frequency = 95 kHz = 95000 Hz. 

Wave speed (or, Wave velocity) = 1500 m/s. 

Wavelength =? 

We know that,

Wave velocity = Frequency × Wavelength 

=> 1500 = 95000 × Wavelength 

=> Wavelength = (1500 ÷ 95000) m. 

=> Wavelength = 0.0158 m. (Approx.)
