Question

The audible frequency range for a human ear is 20Hz -20kHz .convert this into the corresponding wavelength.

Answer 1

Answer:

Explanation:

we know that C = λν

C= speed of light

λ= wavelength

ν= Frequency

C= 3 x 10⁸ m/s

ν₁ = 20 Hz

ν₂ = 20 KHz = 20 x 10³ Hz

Thus the wavelength would be:

=>     λ₁ = 3 x 10⁸ / 20 = 1.5 x 10⁷ m

=>     λ₂ = 3 x 10⁸ / 20 x 10³ = 1.5 x 10⁴ m
