1. What is Wavelength?

Wavelength (λ) is the distance between successive crests of a wave, especially in sound or electromagnetic waves. It is inversely proportional to frequency and directly proportional to the speed of the wave.

2. How Does the Calculator Work?

The calculator uses the wavelength equation:

Where:

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

Explanation: The equation shows that wavelength decreases as frequency increases, and increases with higher wave speed.

3. Importance of Wavelength Calculation

Details: Wavelength calculations are essential in physics, engineering, telecommunications, and audio engineering for designing systems that use wave propagation.

4. Using the Calculator

Tips: Enter wave speed in m/s (for light in vacuum use 299,792,458 m/s), frequency in Hz. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the wavelength of visible light?
A: Visible light ranges from about 380 nm (violet) to 700 nm (red).

Q2: How does wavelength relate to energy?
A: Shorter wavelengths correspond to higher energy photons (E = hc/λ).

Q3: What's the speed of sound for wavelength calculations?
A: Approximately 343 m/s in air at 20°C, but varies with temperature and medium.

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

Q5: What are typical radio wave wavelengths?
A: From about 1 mm (300 GHz) to 100 km (3 kHz).
