Question

Find the wavelength of an electromagnetic wave with frequency 5

Answer 1

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

c

=

λ

⋅

ν

c

=

3.00

×

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

.
