1. What is the Wavelength Formula?

The wavelength formula calculates the distance between consecutive crests of a wave from its frequency and propagation speed. It is fundamental in physics, particularly in wave mechanics and electromagnetic theory.

2. How Does the Calculator Work?

The calculator uses the wavelength formula:

\[ \lambda = \frac{c}{f} \]

Where:

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

3. Importance of Wavelength Calculation

Details: Wavelength calculation is essential in various fields including telecommunications, optics, acoustics, and radio engineering. It helps determine signal characteristics, antenna design, and wave behavior in different media.

4. Using the Calculator

Tips: Enter frequency in Hertz (Hz) and wave speed in meters per second (m/s). For light in vacuum, use c = 3 × 10^8 m/s. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between frequency and wavelength?
A: Frequency and wavelength have an inverse relationship. When frequency increases, wavelength decreases, and vice versa, assuming constant wave speed.

Q2: What is the speed of light used in calculations?
A: The speed of light in vacuum is approximately 3 × 10^8 m/s (299,792,458 m/s exactly). This value is pre-filled as the default speed value.

Q3: Can this calculator be used for sound waves?
A: Yes, simply input the speed of sound (approximately 343 m/s in air at 20°C) instead of the speed of light.

Q4: What are typical wavelength ranges?
A: Wavelengths vary greatly - radio waves can be kilometers long, visible light is 380-750 nm, while gamma rays have wavelengths smaller than atoms.

Q5: How does medium affect wavelength?
A: When waves enter a different medium, frequency remains constant but speed changes, causing wavelength to change proportionally to the speed change.
