Malunga nale khadi
Every wave obeys the same simple relationship: its speed equals its wavelength times its frequency, so wavelength λ = c / f and frequency f = c / λ. For electromagnetic waves in a vacuum the speed is the speed of light, c = 299,792,458 m/s (about 3 × 10⁸ m/s). Because that product is fixed, wavelength and frequency are inversely related — higher frequency always means shorter wavelength. This calculator converts either way, reports the period (T = 1 / f) and the photon energy, and names the electromagnetic band the result falls in, from radio through microwave, infrared, visible light, ultraviolet, X-ray and gamma ray.
As a worked example, an FM radio station at 100 MHz (10⁸ Hz) has a wavelength of λ = 3 × 10⁸ / 10⁸ = 3 metres — which is why FM antennas are on the order of a metre long. Green light at about 5.5 × 10¹⁴ Hz has a wavelength near 545 nm, squarely in the visible band. The tool also returns each photon’s energy from E = h × f, using Planck’s constant h = 6.62607015 × 10⁻³⁴ J·s, and shows it in both joules and electron-volts.
Higher-frequency light carries more energy per photon, which is why blue and ultraviolet light can drive chemical reactions and damage skin while radio waves cannot. You can also override the wave speed under advanced options to model waves in other media — light in glass, or sound in air — where the propagation speed differs from that of light in a vacuum. These conversions are fundamental to radio and antenna design, optics, spectroscopy and understanding the electromagnetic spectrum.
Imibuzo ebuzwa kaningi
Ingabe ubude be-wave nezinga lokusakaza zihlobene?
Zihlobene ngokushintshashintsha ngejubane le-wave: λ = c / f. Ukusakazwa okuphezulu kusho ubude be-wave obuncane, ngoba inzuzo yabo yijubane eliqhubekayo le-light.
Uhlu lwezibalo
Ugesi we-photon yi-E = h × f, lapho h = 6.62607015 × 10⁻³⁴ J·s. Ukukhanya okuphezulu kokuphindaphinda (okuluhlaza okwesibhakabhaka, UV) kuletha amandla amaningi ku-photon kune-light ephansi yokuphindaphinda.
Yini amabhande e-electromagnetic spectrum?
Ngokuya ngezinga lokusakaza elikhulayo: i-radiyo (ngaphansi kwe-~3 GHz), i-microwave, i-infrared, ukukhanya okubonakalayo (~430–770 THz), i-ultraviolet, i-X-ray ne-gamma ray. Amathebula we-calculator akhombisa ibanga lokusakaza lakho.
Ingabe ngizosebenzisa lokhu kumsindo noma izintambo kwezinye izimethrikhi?
Yes. Set the advanced wave-speed field to the speed in your medium — about 343 m/s for sound in air, or roughly 2 × 10⁸ m/s for light in glass — and the wavelength ↔ frequency conversion uses that speed instead of the vacuum speed of light.
Yini isikhathi se-wave?
Isikhathi yisikhathi sosuku olugcwele oluphelele, T = 1 / f. Umsindo we-100 MHz unesikhathi se-10⁻⁸ s (10 nanoseconds). Ithuluzi likhombisa isikhathi esihambisana nokwehla kokwehla.
Ngiguqula kanjani i-wavelength nge-nanometer?
Faka nje - i-calculator ihlela izimpendulo phakathi kwe-pm, nm, µm, mm, m ne km ngokuzenzakalela. Ukukhanya okubonakalayo kuhamba cishe 400 nm (violet) kuya ku-700 nm (red), ngakho-ke 545 nm kungena kuhlala endaweni eluhlaza okwesibhakabhaka yebhande elibonakalayo.
