Question

a wave has a wavelength of 4.0 x 10-7 m and speed of 2.5 x 108 m/s in a particular material. (a) what is its frequency in this material? (b) the frequency of a wave does not change as the wave moves from one material to another. find the wavelength of this wave in vacuum.

Answer 1

a)

`f = 6.25 * {10}^(14) \: hz`

b)

`4.8 * {10}^( - 7) \: m`
