1. What is the Wavelength Formula?

The wavelength formula calculates the distance between consecutive points of the same phase in a wave. For electromagnetic waves, it relates wavelength to frequency through the speed of light.

2. How Does the Calculator Work?

The calculator uses the wavelength formula:

\[ \lambda = \frac{c}{f} \]

Where:

Explanation: The formula shows that wavelength is inversely proportional to frequency - higher frequencies have shorter wavelengths, and vice versa.

3. Importance of Wavelength Calculation

Details: Wavelength calculation is essential in various fields including telecommunications, radio broadcasting, optics, and electromagnetic spectrum analysis. It helps determine the properties and behavior of electromagnetic waves.

4. Using the Calculator

Tips: Enter frequency in Hertz (Hz). The value must be positive and greater than zero. The calculator will automatically compute the corresponding wavelength in meters.

5. Frequently Asked Questions (FAQ)

Q1: What is the speed of light used in the calculation?
A: The calculator uses c = 3×10⁸ m/s, which is the speed of light in vacuum.

Q2: Can this calculator be used for sound waves?
A: No, this calculator is specifically for electromagnetic waves. For sound waves, you would need to use the speed of sound instead of the speed of light.

Q3: What are typical frequency ranges?
A: Radio waves: 3 kHz-300 GHz, Microwaves: 300 MHz-300 GHz, Visible light: 400-790 THz, X-rays: 30 PHz-30 EHz.

Q4: How does wavelength relate to energy?
A: Shorter wavelengths correspond to higher energy photons according to the formula E = hc/λ, where h is Planck's constant.

Q5: What if I need to calculate frequency from wavelength?
A: You can rearrange the formula: f = c/λ. Enter the wavelength to calculate the corresponding frequency.
