Two vertical plane mirrors are inclined at an angle of 60⁰ with each other. A ray of light travelling horizontally is reflected first from one mirror and then from the other. The resultant deviation is

• 60 degree

• 120 degree

• 180 degree

• 240 degree

A ray is reflected in turn by three plain mirrors mutually at right angles to each other. The angle between the incident and the reflected rays is

• 90 degree

• 60 degree
