A point P is 50 mm away from both the reference planes. Draw its all possible projections.

Find the temperature at which there is 1.0 % probability that a state with energy 0.5 eV above Fermi energy will be occupied.

A step index fiber has core refractive index 1.466, cladding refractive index 1.46. If the operating wavelength of the rays is 0.85 μm, calculate the cutoff parameter or normalized frequency and the number of modes which the fiber will support. The diameter of core is 50 μm.

Determine the transition temperature and critical field at 4.2 K for a given specimen of a superconductor if the critical fields are 1.41 × 105 and 4.205 × 105 A/m at 14.1 K and 12.9 K, respectively.

Calculate the probability of an electron occupying an energy level 0.02 eV above the Fermi level at 200 K and 400 K in a material.
