Kalkulaatori info
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.
Korduma kippuvad küsimused
Kuidas on lainepikkus ja sagedus seotud?
Nad on pöördvõrdeliselt seotud läbi laine kiirus: λ = c / f. Suurem sagedus tähendab lühema lainepikkuse, sest nende toode on pidev valguse kiirus.
Kuidas footonenergiat arvutatakse?
Footon on E = h × f, kus h = 6.62607015 × 10−34 J·s. Kõrgema sagedusega valgus (sinine, UV) kannab footoni kohta rohkem energiat kui madalama sagedusega valgus.
Millised on elektromagnetilised spektriribad?
In order of rising frequency: radio (below ~3 GHz), microwave, infrared, visible light (~430–770 THz), ultraviolet, X-ray and gamma ray. The calculator labels which band your frequency falls into.
Kas ma saan seda kasutada heli või lainete jaoks teistes meediates?
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.
Mis on laine periood?
Ajavahemik on aeg ühe täistsükli jaoks, T = 1 / f. 100 MHz laine kestus on 10-8 s (10 nanosekundit). Tööriist annab ajavahemiku ette koos sagedusega.
Kuidas teisendada lainepikkust nanomeetrites?
Sisestage see ® kalkulaatori vormingud tulemused üle pm, nm, μm, mm, m ja km automaatselt. Nähtav valgus töötab umbes 400 nm (violetne) 700 nm (punane), nii et 545 nm sisend maandub roheline osa nähtavat riba.
