1. What is Wavelength?

Wavelength (λ) is the distance between successive crests of a wave, typically measured in meters. It is inversely proportional to frequency and is a fundamental property of waves in physics.

2. How Does the Calculator Work?

The calculator uses the wavelength formula:

Where:

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

Explanation: The equation shows that as frequency increases, wavelength decreases, and vice versa, with the speed of light as the constant of proportionality.

3. Importance of Wavelength Calculation

Details: Wavelength calculation is essential in various fields including telecommunications, optics, astronomy, and electromagnetic theory. It helps determine wave properties and behavior in different media.

4. Using the Calculator

Tips: Enter frequency in Hertz (Hz). The value must be positive and greater than zero. The calculator uses the speed of light in vacuum (3×10⁸ m/s).

5. Frequently Asked Questions (FAQ)

Q1: Why is the speed of light used in the formula?
A: For electromagnetic waves, the speed of propagation in vacuum is constant at approximately 3×10⁸ m/s, represented by 'c'.

Q2: Does wavelength change in different media?
A: Yes, wavelength changes when waves move between different media, though frequency remains constant.

Q3: What is the relationship between frequency and wavelength?
A: They have an inverse relationship - as frequency increases, wavelength decreases, and vice versa.

Q4: Can this calculator be used for sound waves?
A: No, this calculator is specifically for electromagnetic waves. Sound waves use different formulas with the speed of sound instead of light.

Q5: 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.
