A particular form of electromagnetic radiation has a frequency of 4.21 * 1015 Hz. (a) What is the wavelength in nanometers? In meters? Enter your answer in scientific notation.

71 * 10^ - 9 meters

Explanation:

From wave equation

Velocity = frequency * wavelength

Velocity of electronic radiation = 3 * 10^8

Making the wavelength as the subject of formula, we have

Wavelength = Velocity / frequency

= 3*10^8 / 4.21 * 10 ^15

0.71 * 10^-7

In nanometers

We have 0.71 * 10^2 * 10 ^-9

= 71 nanometers
