If speed of sound in air is 340 m / s and in water 1480 m / s and frequency of sound is 1000 kHz then find wavelength of water.

Question

If speed of sound in air is 340 m / s and in water 1480 m / s and frequency of sound is 1000 kHz then find wavelength of water. (A) 1.48 mm (B) 2.96 mm (C) 0.74 mm (D) 1 mm

Tardigrade Admin · Accepted Answer

v=f λ ⇒ 1480=(1000×103)λ ⇒ λ=1.480 mm

Q. If speed of sound in air is $340 m / s$ and in water $1480 m / s$ and frequency of sound is $1000 k Hz$ then find wavelength of water.

1.48 mm

2.96 mm

0.74 mm

1 mm

$v = f λ$
$\Rightarrow 1480 = (1000 \times 1 0^{3}) λ$
$\Rightarrow λ = 1.480 mm$

Q. If speed of sound in air is 340m/s and in water 1480m/s and frequency of sound is 1000kHz then find wavelength of water.
