1. What is Wavelength?

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

2. How Does the Calculator Work?

The calculator uses the wavelength formula:

Where:

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

Explanation: The equation shows that wavelength decreases as frequency increases, when wave speed remains constant.

3. Importance of Wavelength Calculation

Details: Calculating wavelength is essential in physics, engineering, and telecommunications for designing antennas, understanding wave propagation, and analyzing wave behavior in different media.

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) in wavelength.

Q2: How does wavelength relate to energy?
A: Shorter wavelengths correspond to higher energy photons (E = hc/λ, where h is Planck's constant).

Q3: What's the speed of sound in air?
A: Approximately 343 m/s at 20°C (varies with temperature and medium).

Q4: Can wavelength be calculated for any wave type?
A: Yes, the concept applies to all waves - electromagnetic, sound, water waves, etc.

Q5: How does wavelength change in different media?
A: Wavelength changes when wave speed changes, while frequency remains constant.
