Momba ity kapila ity
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.
Fanontaniana matetika
Ahoana no ifandraisan'ny halaviran-doha sy ny isan'ny fisehoana?
Ny hafainganam-pandehan'ny onja dia mifamatotra amin'ny hafainganam-pandehan'ny onja: λ = c / f. Ny fironana avo kokoa dia midika fa ny halavan'ny onja dia fohy kokoa, satria ny vokatry ny hafainganam-pandehan'ny hazavana dia tsy miova.
Ahoana no fomba hisafidianana ny herin'ny photon?
A photon’s energy is E = h × f, where h = 6.62607015 × 10⁻³⁴ J·s. Higher-frequency light (blue, UV) carries more energy per photon than lower-frequency light.
Inona no atao hoe andriamby elektromagnetika?
Araka ny filaharan'ny fironana miakatra: radio (eo ambanin'ny ~3 GHz), microwave, infrared, hazavana hita maso (~430–770 THz), ultraviolet, X-ray ary gamma ray. Ny mari-tsoratra amin'ny milina fanisana izay ahitana ny fironanao.
Azoko ampiasaina amin'ny feo na onjam-peo amin'ny haino aman-jery hafa ve izany?
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.
Inona no fotoana iainan'ny onja iray?
Ny fotoana ahafahana manao tsindry iray feno ny vanim-potoana, T = 1 / f. Ny onjam-peo 100 MHz dia manana vanim-potoana 10⁻⁸ s (10 nanoseconds). Mitatitra ny vanim-potoana miaraka amin'ny isan'ny fihodinana mankany amin'ny toerana misy azy ny fitaovana.
Ahoana no ahafahako manova ny halavan'ny onjam-peo ho nanometra?
Ampidiro fotsiny izany — hametraka ny vokatra amin'ny endrika pm, nm, µm, mm, m ary km ny milina fanisana. Ny hazavana hita maso dia manodidina ny 400 nm (mavokely) ka hatramin'ny 700 nm (mena), ka ny 545 nm dia miditra ao anatin'ny faritra maitso amin'ny faritry ny hazavana hita maso.
