Question

Calculate the wavelength of a wave of frequency 40 mhz propagating in a


medium. [ speed of light = 3 10


8


´ m s


-1


]

Answer 1

wave length=speed *frequency
Hope it will help you

Answer 2

hey, here is your answer...

speed = frequency × wavelength...

3 × 10^8 = 40 × 10^6 × wavelength..

wavelength = (3 × 10^8) ÷ (40 × 10^6)

wavelength = (3 × 10^2) ÷ 40

wavelength = 300 ÷ 40

wavelength = 30 ÷ 4

wavelength = 15 ÷ 2

wavelength = 7.5....
