State the number of images of an object placed between two mirrors, formed in each case when mirrors are inclined to each other at `90^@`

Explanation

To determine the number of images formed by an object placed between two mirrors inclined at an angle of \(90^\circ\), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept**: When two mirrors are inclined at an angle, they create multiple images of an object placed between them. The formula to calculate the number of images formed is given by:
\[ n = \frac{360}{\theta} - 1 \]
