Light is made incident from water to flint glass. The angle of refraction in flint glass is 23.10°. Find the angle of incidence of light on the flint glass from water. The refractive index of water is 1.33 and that of flint glass is 1.62.

Along, straight wire with 3.0 a current flowing through it produces magnetic field strength 1.0 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 36.0% of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire
