Wavelength Formula:
From: | To: |
Wavelength (λ) is the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave. Frequency (f) is the number of waves that pass a fixed point in unit time. The relationship between them is governed by the wave equation.
The calculator uses the wavelength formula:
Where:
Explanation: This formula shows the inverse relationship between wavelength and frequency - as frequency increases, wavelength decreases, and vice versa.
Details: Calculating wavelength is essential in various fields including telecommunications, optics, acoustics, and radio astronomy. It helps determine signal propagation, antenna design, and wave behavior in different media.
Tips: Enter frequency in Hertz (Hz) and the speed of wave propagation in m/s. For electromagnetic waves in vacuum, the speed of light is 3×10^8 m/s by default.
Q1: What is the standard speed of light value?
A: The speed of light in vacuum is exactly 299,792,458 m/s, but is commonly approximated as 3×10^8 m/s for calculations.
Q2: Does the speed change in different media?
A: Yes, the speed of light is slower in materials like water or glass. This affects the wavelength calculation for waves propagating through these media.
Q3: How does frequency relate to energy?
A: For electromagnetic waves, energy is directly proportional to frequency (E = hf, where h is Planck's constant).
Q4: What are typical frequency ranges?
A: Radio waves: 3kHz-300GHz, Microwaves: 300MHz-300GHz, Visible light: 400-790THz, X-rays: 30PHz-30EHz.
Q5: Can this calculator be used for sound waves?
A: Yes, but you need to use the speed of sound (approximately 343 m/s in air at 20°C) instead of the speed of light.
