Wavelength Equation:
From: | To: |
Wavelength is the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave. It is inversely proportional to frequency and directly proportional to the speed of the wave.
The calculator uses the wavelength equation:
Where:
Explanation: The equation shows that as frequency increases, wavelength decreases proportionally, and vice versa.
Details: Calculating wavelength is essential in fields like telecommunications, acoustics, and optics. It helps in designing antennas, understanding sound propagation, and analyzing light properties.
Tips: Enter frequency in Hz and wave speed in m/s. For electromagnetic waves in vacuum, the default speed of light (299,792,458 m/s) is pre-filled. All values must be positive numbers.
Q1: What's the relationship between frequency and wavelength?
A: They are inversely proportional - higher frequency means shorter wavelength, and vice versa, when wave speed is constant.
Q2: Does wavelength change in different media?
A: Yes, because wave speed changes in different media while frequency remains constant, causing wavelength to change.
Q3: What's a typical wavelength for visible light?
A: Approximately 380-750 nanometers (violet to red light in the visible spectrum).
Q4: How does wavelength affect antenna design?
A: Antennas are typically designed to be fractions (½, ¼) of the wavelength they're meant to transmit/receive.
Q5: What's the wavelength of a 100Hz sound wave in air?
A: About 3.43 meters (assuming speed of sound in air is 343 m/s at 20°C).
