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.

Ceisteanna Coitianta

Cén chaoi a bhfuil tonnfhad agus minicíocht a bhaineann?

Tá siad gaolmhar go droim ar ais trí luas na dtonn: λ = c / f. Ciallaíonn minicíocht níos airde tonnfhad níos giorra, ós rud é gurb é a n-ionchur luas leanúnach an tsolais.

Cén chaoi a ríomhtar fuinneamh fótón?

Is é fuinneamh fótón E = h × f, áit a h = 6.62607015 × 10⁻³⁴ J·s. Solas níos airde-minicíocht (gorm, UV) iompraíonn níos mó fuinnimh in aghaidh fótón ná solas níos ísle-minicíocht.

Cad iad na bannaí speictrim leictreamaighnéadacha?

In ord minicíochta ag ardú: raidió (faoi bhun ~3 GHz), micreathonn, infridhearg, solas infheicthe (~430-770 THz), ultraivialait, X-ghathanna agus gathanna gáma.Lipéid an áireamháin ina dtagann do mhinicíocht.

An féidir liom é a úsáid le haghaidh fuaime nó tonnta i meáin eile?

Socraigh an réimse luas tonn chun cinn leis an luas i do mheán — thart ar 343 m / s le haghaidh fuaime san aer, nó thart ar 2 × 108 m / s le haghaidh solas i gloine — agus úsáideann an tonnfhad ↔ comhshó minicíocht an luas sin in ionad luas folúis an tsolais.

Cad é tréimhse na tonn?

Is é an tréimhse an t-am le haghaidh timthriall iomlán amháin, T = 1 / f. Tá tonn 100 MHz tréimhse de 10⁻⁸ s (10 nanashoicind). Tuairiscíonn an uirlis an tréimhse in éineacht leis an minicíocht.

Conas a thiontú mé tonnfhad i nanaiméadair?

Níl ort ach é a iontráil — formáideann an t-áireamhán torthaí thar pm, nm, µm, mm, m agus km go huathoibríoch. Ritheann solas infheicthe thart ar 400 nm (corcra) go 700 nm (dearg), mar sin tagann ionchur 545 nm sa chuid ghlas den bhanna infheicthe.
