Physics Equations:
| From: | To: |
Wavelength (λ) is the distance between successive crests of a wave, frequency (f) is the number of waves that pass a point per second, and energy (E) is the amount of energy carried by each photon of electromagnetic radiation.
The calculator uses the fundamental physics equations:
Where:
Explanation: These equations describe the relationship between the wavelength, frequency, and energy of electromagnetic radiation, following the principles of quantum mechanics.
Details: These calculations are fundamental in physics, chemistry, and engineering for understanding electromagnetic radiation, quantum phenomena, spectroscopy, and various applications in telecommunications, medical imaging, and materials science.
Tips: Enter the wavelength in meters (positive value greater than 0). The calculator will automatically compute the corresponding frequency and energy using the fundamental constants of physics.
Q1: What is Planck's constant?
A: Planck's constant (h) is a fundamental physical constant that relates the energy of a photon to its frequency, with a value of approximately 6.626×10⁻³⁴ joule-seconds.
Q2: How are wavelength and frequency related?
A: Wavelength and frequency are inversely proportional through the speed of light: c = λf, where c is the speed of light (3×10⁸ m/s).
Q3: What units should I use for wavelength?
A: The calculator expects wavelength in meters. For other units (nanometers, micrometers, etc.), convert to meters first (1 nm = 10⁻⁹ m, 1 μm = 10⁻⁶ m).
Q4: Can this calculator handle very small wavelengths?
A: Yes, the calculator can handle wavelengths down to the Planck scale, though extremely small values may approach computational limits.
Q5: What practical applications use these calculations?
A: These calculations are used in spectroscopy, fiber optics, wireless communications, medical imaging (X-rays, MRI), astronomy, and quantum computing.
