Question

A laser emits light with a frequency of 4. 75×1014 s−1. What is the wavelength of this radiation, in nm?.

Answer 1

A Final statement or concluding statement

The equation that relates wavelength, frequency, and speed of light is

c=λ × ν

To find wavelength, λ = c / f

λ = wavelength in meters

ν = frequency in Hertz (Hz) or 1s or $s^{-1}$.

= 3 ×$10^{8}$ m/s / 4. 75 × $10^{14}$ $s^{-1}$(Using velocity of light as 3 x 108 m/s)

= $6.3$×$10^{-7}$m

= $6.3$ × $10^{2}$ nm

How is wavelength related to radiation?

Electromagnetic radiation is an electric and magnetic disturbance that travels at the speed of light through space. It has no mass or charge and travels in packets of radiant energy known as photons or quanta.Radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays, are examples of EM radiation.  Electromagnetic radiation moves at a constant speed in the form of a waveform.

The relationship of velocity to wavelength and frequency reveals the wave characteristics of EM radiation.
