Question

Frequency of 670nm wave?

Answer 1

Step-by-step explanation:

if wavelength =

`670 * {10}^( - 9)`

and

`{wavelength} * frequency = velovity`

take the speed of light to be equal to 3 times 10 to the power of 8

`f = \frac{3 * {10}^(8) }{670 * {10}^( - 9) }`

=4.48 times 10 to the power of 14
