What is the frequency of blue light that has a wavelength of 473nm?

6.34 x 19^14 Hz

Explanation:

Wavelength, λ = 473 nm = 473 x 10^-9 m

the relation between the frequency and the wavelength is given by

v = f x λ

where, v is the velocity of light in vacuum which is equal to 3 x 10^8 m/s.

So, f = v / λ

f = ( 3 x 10^8) / ( 473 x 10^-9)

f = 6.34 x 19^14 Hz
