Velocity Formula:
| From: | To: |
The velocity formula v = f × λ calculates the speed of a wave by multiplying its frequency (f) by its wavelength (λ). This fundamental equation applies to various types of waves including sound waves, light waves, and water waves.
The calculator uses the velocity formula:
Where:
Explanation: The velocity of a wave equals the number of complete wave cycles passing a point per second (frequency) multiplied by the distance between successive wave crests (wavelength).
Details: Calculating wave velocity is essential in physics, engineering, telecommunications, and various scientific fields. It helps determine wave properties, design communication systems, and understand wave behavior in different media.
Tips: Enter frequency in Hertz (Hz) and wavelength in meters (m). Both values must be positive numbers greater than zero for accurate calculation.
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 formula work for all types of waves?
A: Yes, the formula v = f × λ applies to all periodic waves, including electromagnetic waves, sound waves, and mechanical waves.
Q3: How does medium affect wave velocity?
A: Wave velocity changes when moving between different media. For electromagnetic waves, velocity decreases in denser media, while for sound waves, velocity typically increases in denser media.
Q4: What is the relationship between frequency and wavelength?
A: Frequency and wavelength are inversely proportional when velocity is constant. Higher frequency means shorter wavelength, and vice versa.
Q5: Can I calculate frequency or wavelength if I know velocity?
A: Yes, you can rearrange the formula: f = v/λ for frequency or λ = v/f for wavelength if you know the other two values.
