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?

OpenStudy (imtiaz7):

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

OpenStudy (anonymous):

what is the landa

OpenStudy (imtiaz7):

lamda is the wave length of any wave

OpenStudy (anonymous):

so what is the velocity of the wave

OpenStudy (imtiaz7):

just put the values and solve it

OpenStudy (anonymous):

how to find the period

OpenStudy (imtiaz7):

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