Assertion: Therefore is a glass slab between Ram and Anoop. Then, Ram appears nearer to Anoop as compared to the actual distance between them.
Reason: Ray of light starting from Ram will undergo two times refraction before reaching Anoop.

Assertion (A) : The phase difference between any two points on a wave front is zero Reason (R ) : Light from the source reaches every point of the wave front at the same time

Ram and Raj travel along a straight line from X to Y with different unifrom speeds. Ram started from X and reaches the place Y in t s. if Raj travels half of the total distance between X and Y in 2t s, determine the ratio of speevds of Ram and Raj.

Ram and Sham start from a point A.Ram moves towards East to E and Sham moves towards South to S.Draw their paths and name the kind of angle which will be formed between them.

Show that for refraction of light through a parallel glass slab, the incident ray and the emergent ray are parallel to each other. Or, With the help of a diagram show how in case of a rectangular glass slab, when light is refracted by the two parallel faces of the slab, deviation between angle of incidence and angle of refractive is zero.
