c = λf
Where:
* c is the speed of light (approximately 3 x 10⁸ meters per second)
* λ is the wavelength (in meters)
* f is the frequency (in Hertz, Hz)
To find the frequency, you can rearrange the formula to:
f = c / λ
Here's how to calculate the frequency:
1. Identify the wavelength (λ): You'll need to know the wavelength of the wave in meters.
2. Use the speed of light (c): The speed of light is a constant value, approximately 3 x 10⁸ meters per second.
3. Calculate the frequency (f): Divide the speed of light (c) by the wavelength (λ). The result will be the frequency in Hertz (Hz).
Example:
Let's say you have a light wave with a wavelength of 500 nanometers (5 x 10⁻⁷ meters).
1. Wavelength (λ): 5 x 10⁻⁷ meters
2. Speed of light (c): 3 x 10⁸ meters per second
3. Frequency (f): (3 x 10⁸ m/s) / (5 x 10⁻⁷ m) = 6 x 10¹⁴ Hz
Therefore, the frequency of the light wave is 6 x 10¹⁴ Hz.
