Light incident normally on a plane mirror attached to a galvanometer coil reflects backward as shown in figure. A current in the coil produces a deflection of 3.5 0 of the mirror. The displacement of the reflected spot of light on a screen placed 1.0 m away is
Text Solution
Verified by ExpertsThe correct answer is:
C
: Angle of deflection is 
Distance, between the screen and the mirror is = 
m
The reflected rays get deflected by an amount twice the angle of deflection,
i.e.,
