|How it is possible?
For max efficiency= (1+cos(θ)/2.
Then max efficiency is at θ = 0 degrees,
Therefore given statement is incorrect.

|YES, EFFICIENCY IS MAXIMUM FOR 180-degree deflection of incident beam for or theta=0 in above-mentioned formula, given answer is wrong.|

Max. Efficiency=cos^2* α
For this to be max. Alpha should be 0°
