Light with a frequency of 7.18 Ã 1014 hz lies in the violet region of the visible spectrum. what is the wavelength of this frequency of light? answer in units of nm.

The frequency is 7.18 * 10^14 Hz, c = 3 * 10^8 m/s, where c is the speed of light.

But; c = λf, where λ is the wavelength of the wave and f is the frequency.

Making λ the subject, we get;

λ = c/f

= (3 * 10^8) / (7.18 * 10^14)

= 4.17827 * 10^-7 m

but 1 m = 10^9 nm

Therefore;

= (4.17827 * 10^-7) * 10^9

= 417.827 nm

Hence, the wavelength = 417.827 nm
