1. What is the Frequency Wavelength Equation?

The wavelength-frequency equation relates the wavelength (λ) of a wave to its frequency (f) and speed (c). It is fundamental in physics, especially in wave mechanics and electromagnetism.

2. How Does the Calculator Work?

The calculator uses the wavelength equation:

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

Where:

Explanation: The equation shows that wavelength is inversely proportional to frequency when speed is constant.

3. Importance of Wavelength Calculation

Details: Calculating wavelength is essential in fields like radio communications, optics, acoustics, and quantum mechanics. It helps determine wave properties and behavior.

4. Using the Calculator

Tips: Enter frequency in Hertz and wave speed in meters/second. For electromagnetic waves in vacuum, the speed is 3×10⁸ m/s (speed of light).

5. Frequently Asked Questions (FAQ)

Q1: What's the relationship between frequency and wavelength?
A: They are inversely proportional when wave speed is constant - higher frequency means shorter wavelength.

Q2: What are typical wavelength ranges?
A: Radio waves: 1mm-100km, Visible light: 380-750nm, X-rays: 0.01-10nm.

Q3: Does this work for all wave types?
A: Yes, for any wave (sound, light, water waves) as long as you know the speed in that medium.

Q4: Why is speed of light used by default?
A: For electromagnetic waves in vacuum, the speed is constant at approximately 3×10⁸ m/s.

Q5: How does medium affect the calculation?
A: Wave speed changes in different media (slower in denser materials), which affects wavelength for a given frequency.
