1. What is a Frequency vs Wavelength Calculator?

Definition: This calculator determines the wavelength of a wave based on its frequency and propagation speed.

Purpose: It's essential for physics, engineering, radio communications, and any field dealing with wave phenomena.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \lambda \) — Wavelength (meters)
• \( c \) — Speed of wave (meters/second)
• \( f \) — Frequency (Hz)

Explanation: Wavelength is inversely proportional to frequency - higher frequencies have shorter wavelengths.

3. Importance of Wavelength Calculation

Details: Understanding wavelength is crucial for antenna design, wave propagation analysis, and solving interference problems.

4. Using the Calculator

Tips: Enter the frequency in Hz and wave speed in m/s (default 3×10⁸ m/s for light in vacuum). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the speed of light in different media?
A: Light travels slower in other media (e.g., ~2.25×10⁸ m/s in water, ~2×10⁸ m/s in glass).

Q2: How does frequency relate to energy?
A: Higher frequency waves carry more energy (E = hf, where h is Planck's constant).

Q3: What's a typical radio frequency wavelength?
A: For FM radio at 100 MHz: λ = 3×10⁸/10⁸ = 3 meters.

Q4: Can I calculate frequency from wavelength?
A: Yes, simply rearrange the formula: f = c/λ.

Q5: Why is wavelength important for antennas?
A: Antenna length is typically proportional to wavelength (e.g., ¼ or ½ wavelength).
