Light is observed to have a frequency of 1.5x10^14 hz. what is the wavelength of this light? a. 2 m b. 500 nm c. 5m d. 2,000 nm

2 x 10^-6 m

Explanation:

frequency, f = 1.5 x 10^14 Hz

Let the wavelength is λ.

The relation between the frequency and the wavelength is given by

v = f x λ

λ = v / f

λ = ( 3 x 10^8) / (1.5 x 10^14) = 2 x 10^-6 m
