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

Options

  1. A2.96 mm
  2. B2.96 mm
  3. C1.48 mm
  4. D0.74 mm

Correct answer

B. 2.96 mm

Step-by-step solution

Given that, v _ w =1480 ~m / s , f =1000 kHz Speed, v _ w = f = v _ w f = 1480 1000 10^3 =1.480 ~mm
