When a light wave passes from a rarer medium to a denser medium, there will be a phase change of pi radians. This difference brings change in the conditions for constructive and destructive interference. This phenomena also reasons the fromation of interference pattern in thin films like, oily layer, soap film, etc., but has no reason on the shifting of fringes from the central portion outward. The shift is dependent on the refractive index of the material as per the relation, Delta y = (mu - 1) t Thin film interference happens with

When a wave pulse travelling in a string is reflected from rigid wall to which string is tied as shown in figure. For this situation two statements are given below. (1) The reflected pulse will be in same orientation of incident pulse due to a phase change of pi radians (2) During reflection the wall exert a force on string in upward direction

Assertion : Acceleration of a moving particle can change its direction without any change in direction of velocity. Reason : If the direction of change in velocity vector changes, the direction of acceleration vector also changes.
