Wavelength Formula:
| From: | To: |
Wavelength (λ) is the distance between consecutive corresponding points of the same phase on a wave, such as crest to crest or trough to trough. It is a fundamental property of waves that relates to both frequency and velocity.
The calculator uses the wavelength formula:
Where:
Explanation: This formula shows the inverse relationship between wavelength and frequency - as frequency increases, wavelength decreases when velocity is constant.
Details: Calculating wavelength is essential in various fields including physics, engineering, telecommunications, and optics. It helps in understanding wave behavior, designing antennas, analyzing sound waves, and studying electromagnetic radiation.
Tips: Enter velocity in meters per second and frequency in Hertz. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the relationship between wavelength, frequency and velocity?
A: Wavelength is inversely proportional to frequency and directly proportional to velocity, as shown in the formula λ = v/f.
Q2: How does wavelength affect wave properties?
A: Longer wavelengths typically correspond to lower energy waves that can travel farther but carry less information, while shorter wavelengths have higher energy but shorter range.
Q3: What are typical wavelength ranges for different types of waves?
A: Radio waves have the longest wavelengths (1mm-100km), visible light has wavelengths between 380-750nm, and gamma rays have the shortest wavelengths (<10pm).
Q4: How does medium affect wavelength?
A: When a wave moves from one medium to another, its frequency remains constant but its velocity changes, resulting in a change in wavelength.
Q5: Can this formula be used for all types of waves?
A: Yes, the formula λ = v/f applies to all wave types including sound waves, light waves, water waves, and electromagnetic waves.
