An object is placed in front of two plane mirrors inclined at an angle of 0o. If the total number of images formed is 7, Find the value of θ

An object is placed in front of two plane mirrors inclined at an angle of 0o. If the total number of images formed is 7, Find the value of $\theta$

Answer Details

Number of image = $\frac{360}{\theta }$ -1

7 = $\frac{360}{\theta }$ -1

thus,$\theta$ = 45o
