Wavelength Formula:
From: | To: |
Wavelength (λ) is the distance between successive crests of a wave, especially in a sound wave or electromagnetic wave. It is typically measured in meters and is inversely proportional to frequency.
The calculator uses the wavelength formula:
Where:
Explanation: The wavelength is calculated by dividing the wave's speed by its frequency.
Details: Calculating wavelength is essential in physics, engineering, and telecommunications for designing systems that use wave propagation, such as radio, sound, and light systems.
Tips: Enter the wave speed in m/s and frequency in Hz. Both values must be positive numbers.
Q1: What is the speed of light used for electromagnetic waves?
A: The speed of light in a vacuum is approximately 299,792,458 m/s (often rounded to 3×10⁸ m/s).
Q2: How does wavelength relate to energy?
A: For electromagnetic waves, shorter wavelengths correspond to higher energy photons (E = hc/λ, where h is Planck's constant).
Q3: What is the typical wavelength range for visible light?
A: Approximately 380-750 nanometers (1 nm = 10⁻⁹ m).
Q4: How does wavelength affect sound perception?
A: In sound waves, wavelength determines pitch - shorter wavelengths produce higher-pitched sounds.
Q5: Can this calculator be used for water waves?
A: Yes, as long as you know the wave speed and frequency in the medium.
