1. What is the Wavelength Equation?

The wavelength equation (λ = v / f) calculates the distance between consecutive corresponding points of the same phase on a wave, such as crest-to-crest or trough-to-trough. It relates the wave's velocity (v) to its frequency (f).

2. How Does the Calculator Work?

The calculator uses the wavelength equation:

Where:

• \( \lambda \) — Wavelength (meters)
• \( v \) — Velocity of the wave (meters per second)
• \( f \) — Frequency of the wave (Hertz)

Explanation: The equation shows that wavelength is inversely proportional to frequency - as frequency increases, wavelength decreases, assuming constant velocity.

3. Importance of Wavelength Calculation

Details: Calculating wavelength is essential in various fields including physics, engineering, telecommunications, and optics. It helps determine wave properties and behavior in different media.

4. Using the Calculator

Tips: Enter velocity in m/s and frequency in Hz. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between wavelength and frequency?
A: Wavelength and frequency have an inverse relationship. As frequency increases, wavelength decreases, and vice versa, when wave velocity remains constant.

Q2: Does wavelength change in different media?
A: Yes, when a wave moves from one medium to another, its velocity changes, which affects its wavelength while frequency remains constant.

Q3: What are typical wavelength values for visible light?
A: Visible light wavelengths range from approximately 380 nanometers (violet) to 750 nanometers (red).

Q4: How does wavelength relate to energy?
A: For electromagnetic waves, shorter wavelengths correspond to higher energy photons, following the equation E = hc/λ.

Q5: Can this equation be used for all types of waves?
A: Yes, the equation λ = v/f applies to all wave types including sound waves, water waves, and electromagnetic waves.
