Things around you are emitting infrared radiation that includes the wavelength 1.03 10 m. What is the energy of these IR photons? eV Gamma rays (γ-rays) are high-energy photons. In a certain nuclear reaction, a γ-ray of energy 0.779 MeV (million electronvolts) is produced. Compute the frequency of such a photon. Infrared (IR) radiation is a form of electromagnetic radiation with longer wavelengths compared to visible light. To find the energy of IR photons emitting at a wavelength of 1.03 × 10 -6 meters, we employ the relation between energy and wavelength of photons. The photon energy (E) is given by the Planck relation: E = hν = hc / λ where: h = Planck's constant = 6.626 × 10 -34 Joule·seconds c = speed of light = 3.00 × 10 8 meters/second λ = wavelength = 1.03 × 10 -6 meters Calculating the energy in Joules: E = (6.626 × 10 -34 ) × (3.00 × 10
