Calculation Results

Electromagnetic Band
Microwaves
Wavelength (λ)
12.49 cm
Typical Real-World Uses
Wi-Fi (2.4/5 GHz), 5G Mobile phones, Radar, Microwave ovens
Photon Energy
9.926e-6 eV (1.590e-24 J)
Summary: A frequency of 2,400 MHz has a wavelength of 12.49 cm and belongs to the Microwaves spectrum (Wi-Fi (2.4/5 GHz), 5G Mobile phones, Radar, Microwave ovens).
Step-by-Step Calculation Solution
1.Wavelength λ = c / f = 299,792,458 m/s / 2.400e+9 Hz = 0.1249 m (12.49 cm)
2.Photon Energy E = h × f = 1.590e-24 Joules = 9.926e-6 eV

Formula & How Electromagnetic Waves & Frequency Calculator Works

Mathematical Formula
Wavelength λ = c / f | Photon Energy E = h × f

All electromagnetic waves travel at the speed of light (c). Higher frequencies (like Gamma rays and X-rays) have shorter wavelengths and higher photon energy, whereas lower frequencies (Radio and Microwaves) have longer wavelengths.

How to Calculate Electromagnetic Waves & Frequency Calculator (Step-by-Step)
  1. Enter Frequency in Megahertz (MHz): Input your target parameter value.
  2. Apply Formula: Calculate using Wavelength λ = c / f | Photon Energy E = h × f.
  3. Review Results: View exact computed answers, metrics, and worked mathematical proofs.
