Wavelength Formula:
| From: | To: |
Wavelength calculation determines the distance between consecutive corresponding points of the same phase on a wave, such as crest-to-crest or trough-to-trough. It's a fundamental concept in wave physics and acoustics.
The calculator uses the wavelength formula:
Where:
Explanation: This formula shows the inverse relationship between frequency and wavelength - as frequency increases, wavelength decreases, and vice versa, when wave speed remains constant.
Details: Calculating wavelength is essential in various fields including acoustics, optics, radio communications, and musical instrument design. It helps determine how waves interact with their environment and with each other.
Tips: Enter wave speed in m/s and frequency in Hz. Both values must be positive numbers. The default values (440 m/s and 220 Hz) represent a common sound wave example.
Q1: What is the relationship between wavelength and frequency?
A: Wavelength and frequency have an inverse relationship when wave speed is constant. Higher frequency means shorter wavelength, and lower frequency means longer wavelength.
Q2: Why is 440 m/s used as a default value?
A: 440 m/s is approximately the speed of sound in air at room temperature (20°C), making it a common reference point for sound wave calculations.
Q3: How does medium affect wave speed and wavelength?
A: Different media (air, water, solids) have different wave speeds, which affects wavelength calculation for the same frequency.
Q4: Can this calculator be used for light waves?
A: Yes, the same formula applies, but you would use the speed of light (approximately 3×10⁸ m/s) instead of the speed of sound.
Q5: What are typical wavelength ranges for sound waves?
A: Audible sound wavelengths range from about 17 meters (20 Hz) to 1.7 centimeters (20,000 Hz) in air at room temperature.
