## 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.
