Wavelength Formula:
From: | To: |
Wavelength (λ) is the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave. It is a fundamental property of waves that determines many of their characteristics.
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 crucial in various fields including telecommunications, acoustics, optics, and radio engineering. It helps determine antenna sizes, sound properties, light behavior, and many other wave-related phenomena.
Tips: Enter the speed of wave propagation in m/s and frequency in Hz. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the speed of light used in electromagnetic wave calculations?
A: The speed of light in vacuum is approximately 299,792,458 m/s (often rounded to 3×10⁸ m/s for calculations).
Q2: How does wavelength relate to energy?
A: For electromagnetic waves, shorter wavelengths correspond to higher energy photons according to the formula E = hc/λ, where h is Planck's constant.
Q3: What are typical wavelength ranges for visible light?
A: Visible light wavelengths range from approximately 380 nm (violet) to 750 nm (red).
Q4: Can this formula be used for sound waves?
A: Yes, the same formula applies to sound waves, where c represents the speed of sound in the medium (approximately 343 m/s in air at 20°C).
Q5: How does medium affect wavelength?
A: When a wave moves from one medium to another, its frequency remains constant but its speed changes, resulting in a change in wavelength.
