Question

Compute the wavelength in air of ultrasound with a frequency of 38 kHz if the speed of sound is 344 m/s.answer in:____ m

Answer 1

Answer:

λ = 0.0091 m

Explanation:

The frequency, f = 38 kHz

f = 38000 Hz

The speed, v = 344 m/s

The wavelength is calculated using the formula:

λ = v/f

Substitute f = 38000 Hz and v = 344 m/s into the formula and solve for λ

λ = 344/38000

λ = 0.0091 m
