Question

(a) The magnification produced by a mirror is given by m = -v/u. What does the magnitude of magnification signify?

(b) In which of the medium is the speed of light highest? Given below the values of refractive index in the brackets, Kerosene (1.47), Ice (1.31), CS, (1.62)​

Answer 1

Answer:-

a) Magnification produced by a spherical mirror gives the relative extent to which the image of an object is magnified with respect to the object size.

b) In CS, the speed of light is highest. Because the refractive index of CS is comparatively highest then kerosene and ice.
