Question

1.5), both surfaces of which are partly metallized to increase A glass plate (n their reflectivity, may form two virtual images due to reflections from its external and internal surfaces. What are the refractive indexcs in the two image spaces? (0.5p) What is the difference between thin-film interference patterns observed in the reflected and refracted lights from the same film? (0.5p) A metal ring with a radius a and a total resistivity R is placed in a magnetic field B parallel to the main axis of the ring. The ring is rotated about an axis perpendicular to B with an angular velocity w. Find electric current in the ring. (lp)
