Question

an electromagnetic wave with a wavelength of 6.0*10^-7M travels at the speed of light:3.0*x10^8m/s
A) what is the frequency of this wave?
B) What is the Wave's period?

Answer 1

V=fΛ
f=V/Λ
put the values of velocity and wave length we get the speed of that wave.

Answer 2

what is the landa

Answer 3

lamda is the wave length of any wave

Answer 4

so what is the velocity of the wave

Answer 5

just put the values and solve it

Answer 6

how to find the period

Answer 7

when we get frequency the we'll find the period by:
period=1/f
