Frequency of Light Calculator

To calculate the frequency of light, divide the speed of light by its wavelength. The Frequency of Light Calculator is a valuable tool for determining the frequency of light waves based on their wavelength.

This calculation is crucial in physics and optics to understand the behavior of electromagnetic waves, including visible light, infrared, and ultraviolet radiation.

By using this calculator, you can easily convert between wavelength and frequency, enabling better insights into light’s energy and properties.

Formula:

f = c / w

Symbol	Meaning	Description
$f$	Frequency (Hz)	Number of wave cycles per second
$c$	Speed of Light (m/s)	Constant value of $3 \times 10^8 \, \text{m/s}$
$w$	Wavelength (m)	Distance between two peaks of the light wave

Solved Calculations:

Example 1: Find the frequency of light with a wavelength of $700 \, \text{nm}$ (red light).

Step	Calculation	Result
Convert $w$ to meters	$w = 700 \, \text{nm} = 700 \times 10^{-9} \, \text{m}$	$w = 7 \times 10^{-7} \, \text{m}$
Apply the formula	$f = c / w = 3 \times 10^8 / 7 \times 10^{-7}$	$f = 4.29 \times 10^{14} \, \text{Hz}$

Step	Calculation	Result
Convert $w$ to meters	$w = 500 \, \text{nm} = 500 \times 10^{-9} \, \text{m}$	$w = 5 \times 10^{-7} \, \text{m}$
Apply the formula	$f = c / w = 3 \times 10^8 / 5 \times 10^{-7}$	$f = 6 \times 10^{14} \, \text{Hz}$
