1. What is the Wavelength Equation?

The wavelength equation (λ = v / f) calculates the distance between consecutive crests of a wave, where λ is wavelength, v is wave velocity, and f is frequency. It's fundamental in physics for understanding wave behavior.

2. How Does the Calculator Work?

The calculator uses the wavelength equation:

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

Where:

Explanation: The equation shows the inverse relationship between frequency and wavelength - as frequency increases, wavelength decreases, assuming constant velocity.

3. Importance of Wavelength Calculation

Details: Wavelength calculation is essential in acoustics, optics, radio communications, and many other fields where wave properties need to be analyzed and applied.

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 standard speed of sound in air?
A: Approximately 343 m/s at 20°C, but it varies with temperature, humidity, and altitude.

Q2: How does wavelength relate to pitch in sound?
A: Shorter wavelengths correspond to higher frequencies, which we perceive as higher pitch sounds.

Q3: Can this equation be used for light waves?
A: Yes, with v = c (speed of light ≈ 3×10⁸ m/s), the equation calculates wavelength of electromagnetic waves.

Q4: What are typical wavelength ranges for sound?
A: Human hearing range (20Hz-20kHz) corresponds to wavelengths from about 17 meters to 1.7 centimeters in air.

Q5: How does medium affect wave velocity?
A: Sound travels faster in solids than liquids, and faster in liquids than gases due to differences in density and elasticity.
