Question

What is the frequency of a red light with a wavelength of 6.98 x 10^-6

Answer 1

frequency of light =
`4.2* 10^(-13)`

Step-by-step explanation:

we know that relation between frequency and wavelength of light is

frequency × wavelength = speed of light.

therefore frequency =
`(c)/(wavelength)`

=
`(3* 10^(8))/(6.98* 10^(-6))`

=
`4.2* 10^(-13)`
