What is the wavelenth of the 0.186 MeV gamma- ray photon emitted by radium ._(88)^(226) Ra ?

What is the wavelenth of the 0.186 MeV gamma- ray photon emitted by radium ._(88)^(226) Ra ?

A pulsed laser emits light at a wavelength of 694.4 nm. The pulse duration is 12 ps, and the energy per pulse is 0.150 J. (a) What is the length of the pulse? (b) How many photons are emitted in each pulse?

The passage of gamma -rays photons through materials sometimes results in pair production, i.e., the transformation of a gamma -rays photon into a positron and an electron (eachof mass m). What is the maximum wavelength of gamma - ray photons for which pair production is possible? (c = speed of light, h = plank constant)

A The wavelength of the K_alpha line ofthe characteristic X rays emitted by an element is 0.64 Å . What is the wavelength of K_beta line emitted by the same element?

The alpha particles emitted by radium have energies of 4.777MeV and 4.600MeV .What is the wavelength in pm of the gamma rays accompanying the decay? The difference in energies of alpha particle emitted out is equal to the energy of gamma rays.Report your answer to nearest integer. (h=6.626times10^(-34) Joule.sec,charg "]
