Respuesta :

The frequency of this light is 4.61 x 10¹⁴ Hz

Explanation:

We have equation for speed of electromagnetic wave,

               c = fλ

Where

           f is the frequency and λ is the wavelength.

Here

            c = 3.0×10⁸ m/s

            λ = 6.5×10⁻⁷ m

Substituting in c = fλ

              3.0×10⁸ = f x 6.5×10⁻⁷

               f = 4.61 x 10¹⁴ Hz

The frequency of this light is 4.61 x 10¹⁴ Hz
