1. What is a Wavelength Calculator?

Definition: This calculator determines the wavelength of electromagnetic waves based on frequency and the speed of light.

Purpose: It helps physicists, engineers, and students calculate wavelength for radio waves, light, and other electromagnetic radiation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The speed of light is divided by the frequency to determine the physical length of one wave cycle.

3. Importance of Wavelength Calculation

Details: Wavelength calculations are essential for antenna design, optical systems, spectroscopy, and understanding wave propagation.

4. Using the Calculator

Tips: Enter the frequency in Hz and speed of light (default 3 × 10⁸ m/s). For other media, adjust the speed value accordingly.

5. Frequently Asked Questions (FAQ)

Q1: What's the relationship between frequency and wavelength?
A: They are inversely proportional - higher frequencies have shorter wavelengths.

Q2: When would I change the speed of light value?
A: When calculating wavelength in media other than vacuum (e.g., ~2.25e8 m/s in water).

Q3: What frequency range does this work for?
A: The formula works for all electromagnetic frequencies, from radio waves to gamma rays.

Q4: How precise is this calculation?
A: The precision depends on your input values. The calculator shows 6 decimal places.

Q5: Can I calculate frequency from wavelength?
A: Yes, simply rearrange the formula: \( f = \frac{c}{\lambda} \).
