Two light waves are initially in phase and have the same wavelength, 470 nm. They enter two different media of identical lengths of 2.50 µm. If n1 = 1.2 and n2 = 1.5, what is the effective phase difference of the waves when they exit the media? Group of answer choices 3.7 rad 10 rad 1.6 rad 0.6 rad 0 rad

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
