1. What is the Velocity Equation?

The velocity equation (v = f × λ) calculates the speed of a wave by multiplying its frequency (f) by its wavelength (λ). This fundamental physics equation applies to various wave types including sound waves, light waves, and water waves.

2. How Does the Calculator Work?

The calculator uses the velocity equation:

Where:

• \( v \) — Velocity (m/s)
• \( f \) — Frequency (Hz)
• \( \lambda \) — Wavelength (m)

Explanation: The equation shows the direct proportional relationship between wave velocity and both frequency and wavelength.

3. Importance of Velocity Calculation

Details: Calculating wave velocity is essential in physics, engineering, telecommunications, and various scientific fields for understanding wave behavior, signal transmission, and wave propagation through different media.

4. Using the Calculator

Tips: Enter frequency in Hertz (Hz) and wavelength in meters (m). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for the calculation?
A: Frequency should be in Hertz (Hz) and wavelength in meters (m) to get velocity in meters per second (m/s).

Q2: Does this equation work for all types of waves?
A: Yes, the equation v = f × λ applies to all wave types including electromagnetic waves, sound waves, and mechanical waves.

Q3: What if I know velocity and frequency but need wavelength?
A: You can rearrange the equation: λ = v ÷ f

Q4: What if I know velocity and wavelength but need frequency?
A: You can rearrange the equation: f = v ÷ λ

Q5: How does the medium affect wave velocity?
A: Wave velocity changes with the properties of the medium. For example, sound travels faster in water than in air, and light travels slower in glass than in vacuum.
