Question

If the angle between the mirrors is 90⁰, _____ images can be seen.

(a) 7 (b) 8 (c) 3 (d) 4​

Answer 1

Answer:

we use this formula 360^./n -1

360/90 -1

4-1

3 image are formed by mirror

Answer 2

$\huge\mathfrak\pink{Given:}$

⟹ Angle between two mirror is 90°

$\huge\mathcal\color{yellow}Find:$

⟹ No.of images .

$\huge\mathfrak\color{aqua}★\:Formula\:★$

⟹ $n = \frac{360°}{A \:} - 1$

$\huge\mathrm\orange{Explanation:}$

$⇒n = \frac{360°}{A \:} - 1 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\⇒ n = \frac{360°}{90 °} - 1 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\⇒n = 4 - 1 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \\ \\ ⇒n = 3 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ n \: = \: number \: of \: image \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ A \: = angle \: between \: the \: mirror \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

⇒ number images formed = 3
