Tentang kalkulator ini
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.
Sering kali mengajukan pertanyaan
Bagaimana panjang gelombang dan frekuensi berhubungan?
They are inversely related through the wave speed: λ = c / f. A higher frequency means a shorter wavelength, since their product is the constant speed of light.
Bagaimana energi foton dihitung?
Sebuah foton berenergi E = h × f, di mana h = 6.62607015 × 10 J·s. Cahaya frekuensi tinggi (biru, UV) membawa lebih banyak energi per foton daripada cahaya frekuensi rendah.
Apa itu spektrum elektromagnetik?
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.
Dapatkah saya menggunakannya untuk suara atau gelombang di media lain?
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.
Berapa periode gelombang?
Periode ini adalah waktu untuk satu siklus penuh, T = 1 / f A 100 MHz gelombang memiliki periode 10 Allaht8 s (10 nanodetik). Alat ini melaporkan periode di samping frekuensi.
Bagaimana cara mengubah panjang gelombang dalam nanometres?
Masukkan saja format kalkulatornya pada jam pm, nm, mm, m, dan km secara otomatis. Cahaya terlihat berjalan sekitar 400 nm (violet) sampai 700 nm (merah), jadi 545 nm input tanah di bagian hijau dari band yang terlihat.
