Question

Can someone explain in detail how to do this problem? A ruby laser emits red light at a wavelength of 694.3 nm andan X-ray generator emits radiation with a wavelength of 1.544Angstroms. How many more times energetic is a single X-ray photonof this wavelength than a photon emitted by a ruby laser? Answer: 2 Can someone explain in detail how to do this problem? A ruby laser emits red light at a wavelength of 694.3 nm andan X-ray generator emits radiation with a wavelength of 1.544Angstroms. How many more times energetic is a single X-ray photonof this wavelength than a photon emitted by a ruby laser? Answer: 2

Explanation / Answer

you want to use energy= h frequ h is planks contant so compare the 2 by dviding the 2 energysso... (6.6260755E-34*(3e8/1.544e-10))/ (6.6260755E-34*(3e8/6.943e-7)) top one is xray bottom is laser so xray/laser is energy change the answer is 4496.76
