Question

Calculate the wave length of the radiation emited with a frequency of , 1200kHz (c=3.0x10^8m/s)

Answer 1

The equation that relates wavelength, frequency, and speed of light is

c

=

λ

⋅

ν

c

=

3.00

×

10

8

m/s

(the speed of light in a vacuum)

λ

= wavelength in meters

ν

= frequency in Hertz (Hz) or

1

s

or

s

−

1

.

So basically the wavelength times the frequency of an electromagnetic wave equals the speed of light.

FYI,

λ

is the Greek letter lambda , and

ν

is the Greek letter nu (it is not the same as a v).

To find wavelength (

λ

), the equation is manipulated so that

λ

=

c

ν

.
