what is the conditions to produce two coherent*
Write the two basic rules which dertmine the structure of many electron atoms
write the expression of internal energy for the solid crystal according to the Einstein & Classical theriores .Via specific heat definition show their discrepancy *
explain the mechanism of cooper pair production *
Calculate range of alpha particles in Ni64,it ’s energy was 9 Mev*
Define Impulse *
*For pnp transistor ,draw the biased circuit to get 1-vltage and current gain 2- only voltage gain ,3- only current gain lens of focal length f is used project an image of a solar ellipse on a flat sheet of paper ,which of the following images in this case 1-f/2 ,2- f ,3-more than 4- 10f ,5- less than f/10 ,6- none of the above
*When light goes from one medium to another medium with a different index of refraction which of the following do (does ) not change 1- the speed ,2- wave length ,3- frequency ,4- speed & frequency ,5- frequency & wave length
