Wavelength Calculator
λ = c / f
Calculate the wavelength of light given its frequency. Enter the frequency in Hz.
Wavelength Calculator Purpose:
The Wavelength Calculator helps determine the wavelength of light or other electromagnetic waves when the frequency is known. It uses the formula:
lambda(λ) = (v)/(ƒ)
- λ (lambda) is the wavelength,
- c is the speed of light in a vacuum, approximately 299,792,458299,792,458299,792,458 meters per second (m/s), and
- f is the frequency in hertz (Hz).
This tool is useful in physics, optics, and telecommunications to understand the properties of waves.
How to Use:
- Open the Tool: Navigate to the Wavelength Calculator page on your web browser.
- Enter the Frequency:
- In the "Enter Frequency (f)" input field, type the frequency of the wave in hertz (Hz).
- Calculate the Wavelength:
- Click the "Calculate" button. The tool will use the formula λ=cf\lambda = \frac{c}{f}λ=fc to calculate the wavelength.
- View the Result:
- The calculated wavelength will be displayed in the "Wavelength (λ)" field and in the result box below the form.
- Reset:
- Click the "Reset" button to clear the fields and results, allowing you to enter a new frequency for another calculation.
Example Use:
Scenario: Calculate the wavelength of a light wave with a frequency of 5×10145 \times 10^{14}5×1014 Hz.
- Frequency (f): Enter
5e14
(which stands for 5×10145 \times 10^{14}5×1014 Hz). - Calculate: Click "Calculate" to find the wavelength.
- Result: The tool will display "Wavelength (λ) = 5.996e-07 m".
This result shows that the wavelength of light with the given frequency is approximately 599.6 nanometers.
