1. What is the Wavelength Equation?

The wavelength equation calculates the wavelength of electromagnetic waves using the speed of light and frequency. It is a fundamental equation in physics and wave mechanics.

2. How Does the Calculator Work?

The calculator uses the wavelength equation:

Where:

• \( \lambda \) — Wavelength (meters)
• \( c \) — Speed of light (3×10⁸ m/s)
• \( f \) — Frequency (Hz)

Explanation: The equation shows the inverse relationship between wavelength and frequency - as frequency increases, wavelength decreases.

3. Importance of Wavelength Calculation

Details: Wavelength calculation is essential in various fields including telecommunications, optics, astronomy, and electromagnetic spectrum analysis.

4. Using the Calculator

Tips: Enter frequency in Hertz (Hz). The value must be positive and greater than zero for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the speed of light constant?
A: The speed of light in vacuum is exactly 299,792,458 m/s, but is commonly approximated as 3×10⁸ m/s for calculations.

Q2: Can this calculator be used for sound waves?
A: No, this calculator is specifically for electromagnetic waves. Sound waves use different speed values depending on the medium.

Q3: What are typical frequency ranges?
A: Radio waves: 3 Hz-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 equation E = hc/λ, where h is Planck's constant.

Q5: What if I need to calculate for different media?
A: For media other than vacuum, use the appropriate speed of light for that medium (c = c₀/n, where n is refractive index).
