Question

The wavelength of wave is 1 cm and
frequeny of wave is 40 KHz then find
the speed of wave.​

Answer 1

Answer:

Explanation:

WAVELENGTH,λ=1 CM=10^-2 M

FREQUENCY,υ=40*10^3 HZ

                         =4*10^4 HZ

SPEED OF THE WAVE=?

VELOCITY=WAVELENGTH*FREQUENCY.

V=10^-2*4*10^4

 =4*10^2

 =400 M/S.
