Question

If the mirrors are inclined to each other at an angle 40º,calculate the number of images formed.

Answer 1

Answer:

9

no. of images formed would be 8or9

Answer 2

Answer:

if object is symmetrically placed = 8

if object is asymmetrically placed = 9

Explanation:

If , the object is symmetrically placed.

then

$\boxed{\sf No. \: of \: image (n)=\dfrac{360}{\theta}-1}$

➞ n = 360/40-1

➞ n = 8

No. of images will be 8 if object is symmetrically placed.

If , the object is asymmetrically placed.

then

$\boxed{\sf No. \: of \; images (n) =\dfrac{360}{\theta}}$

➞ n = 360/40

➞ n = 9

No. of images will be 9 if object is asymmetrically placed
