Your answer is partially correct. A spectral emission line is electromagnetic radiation that is emitted in a wavelength range narrow enough to be taken as a single wavelength. One such emission line that is important in astronomy has a wavelength of 21 cm. What is the photon energy in the electromagnetic wave at that wavelength? Number 9.465714286 Units eV
A spectral emission line is electromagnetic radiation that is emitted in a wavelength range narrow enough to be taken as a sin-gle wavelength. One such emission line that is important in astronomy has a wavelength of 21 cm.What is the photon energy in the electromagnetic wave at that wavelength?
A helium-neon laser emits a light beam with a wavelength of 633 nm. The power of the laser beam is 1.0 mW. What is the energy of one photon of laser light? How many photons does the laser emit each second?
