An atom has an energy level 1.8 eV above ground state. When excited, it returns to the ground state and emits a photn. Ccalculate the energy and wavelength of the photon.
help me please
thank you

Nope, it was Einstein who came up with the whole "photon" thing in his paper on the photo-eletric effect, which got him the Nobel Price.
The formula for calculating the energy of a photon is E = hν, where E is energy, h is Planck's constant (6.626 x 10^-34 J·s), and ν is the frequency of the photon.
The wavelength of a photon can be determined by dividing the speed of light (c = 3.00 x 10^8 m/s) by the frequency of the photon (λ = c/ν).
The energy and wavelength of a photon are inversely proportional. This means that as the energy of a photon increases, the wavelength decreases and vice versa.
Yes, the energy and wavelength of a photon can be calculated for any type of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
The energy and wavelength of a photon are used in various scientific fields, such as astronomy, quantum mechanics, and spectroscopy. They are important in understanding the behavior and properties of electromagnetic radiation and its interactions with matter.
