A nuclear scientist claimed that he has accurately measured the energy and momentum of radiation (alpha’ beta’ gamma-ray etc.) using his most sensitive geiger muller counter. Can you believe his claim is correct? If yes give a proper justification of his claim and if no then also justify it
can we find the energy and momentum of radiation at a same time by geiger muller counter??
In the Stern-Gerlach experiment a beam of silver atoms were made to pass through a long, narrow gap which had an inhomogeneous transverse magnetic eld. The direction of the eld is the same, and perpendicular to the atomic beam, at all points in the gap. The expected and observed images of the beam with the magnetic eld are shown in the gure below. Stern and Gerlach had assumed that the silver atoms were in an L = 1 state. In hindsight, is their observation consistent with their assumptions? What is a reasonable conclusion from this experiment

 The original Rutherford scattering experiment was done using 5 MeV alpha particles incident on a gold target (Z = 79). Suppose, that this experiment had been instead done with 10 MeV alpha particles incident on a silver foil (Z = 47). Discuss the implications of the outcomes of these experiments on the determination of the size of the nucleus


What is the wavelength of an electron moving at 5.31×10⁶m/sec?


A molecule has r.m.s speed of 550m/s at temperature of 20°c.what is its r.m.s speed at 80°c


 Two radioactive nuclides, S and M, both have the same activity X at time t = 0. S and M have a half-life of 26 years and 16 years respectively. Now both samples S and M are mixed. Find out the total activity of the mixture at t = 50 years?
