Let a plane-reflect and a settled episode beam of light reflecting from the surface at a point θ Before the pivot of the mirror, the frequency edge is θ just like the reflection angle.If the mirror is turned through an edge φ the typical is pivoted by an edge &phi and subsequently the edge of rate increments to θ +φ. In this way, the edge of reflection should likewise increment by φ to θ+φ The distinction between the last point of reflection and the underlying edge of reflection and is 2φ
For a settled episode beam, the edge of the reflection is double the point through which the mirror has pivoted.
In this way the point of Deviation in plane mirror is 2φ.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
