Statement-I: The twinkling of star is due to reflection of light.
Statement-II: The velocity of light changes while going from one medium to the other.
Statement-II: The velocity of light changes while going from one medium to the other.
View answer and explanation
Correct option: D
If Statement-I is false but Statement-II is true.
Option D (If Statement-I is false but Statement-II is true) is correct because the twinkling of stars is due to atmospheric refraction, not reflection, and the velocity of light does change when it enters a different medium.

An object 5 cm tall is placed from a concave spherical mirror which has a radius of curvature of . The size of the image is
Red colour is used for danger signals because
A ray of light is incident on the hypotenuse of a right-angled prism after travelling parallel to the base inside the prism. If is the refractive index of the material of the prism, the maximum value of the base angle for which light is totally reflected from the hypotenuse is
Statement-A: The minimum distance between an object and its real image formed by a convex lens is .
Statement-B: The distance between an object and its real image is minimum when its magnification is -1. Assertion: We cannot produce a real image by plane or convex mirrors under any circumstances.
Reason: The focal length of a convex mirror is always taken negative. If both the object and image are at infinite distance from a refracting telescope its magnifying power will be equal to
