Wavelength Formula:
| From: | To: |
The wavelength formula calculates the distance between consecutive points of a wave that are in phase. It is a fundamental concept in physics, particularly in wave mechanics and electromagnetic theory.
The calculator uses the wavelength formula:
Where:
Explanation: The formula shows the inverse relationship between wavelength and frequency - as frequency increases, wavelength decreases, and vice versa.
Details: Wavelength calculation is essential in various fields including optics, radio communications, acoustics, and quantum mechanics. It helps determine wave properties and behavior in different media.
Tips: Enter frequency in Hertz (Hz) and speed of light in meters per second (m/s). The default speed of light value is set to 300,000,000 m/s (3×10⁸ m/s). All values must be positive numbers.
Q1: What is the relationship between wavelength and frequency?
A: Wavelength and frequency have an inverse relationship. As frequency increases, wavelength decreases, and vice versa, when the wave speed remains constant.
Q2: Does the speed of light change in different media?
A: Yes, the speed of light changes when it passes through different media. In vacuum, it's approximately 3×10⁸ m/s, but it slows down in materials like water or glass.
Q3: What are typical wavelength ranges for different types of electromagnetic waves?
A: Radio waves have the longest wavelengths (1mm-100km), followed by microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays with the shortest wavelengths.
Q4: How does wavelength affect wave behavior?
A: Wavelength determines how waves interact with objects. Longer wavelengths can diffract around obstacles more easily, while shorter wavelengths are more directional and have higher energy.
Q5: Can this formula be used for sound waves?
A: Yes, the same formula applies to sound waves, but the speed value would be the speed of sound in the specific medium (approximately 343 m/s in air at 20°C).
