Solution

The correct option is B 11
By using $δ = (360 - 2 θ) \Rightarrow 300 = 360 - 2 θ$
$\Rightarrow θ = 30^{\circ}$ .Hence number of images = $\frac{360}{30} - 1 = 11$

A ray reflected successively from two plane mirrors inclined at a certain angle undergoes a deviation of 300∘. The number of images observable are

The correct option is B 11By using δ=(360−2θ)⇒300=360−2θ ⇒θ=30∘.Hence number of images =36030−1=11
