Answer 1

Given:

• The angle between 2 mirrors is 45°

To Find:

• The number of images formed

Solution:

★ We know that,

$\: \: \: \: \: \dag \: \: \: \bigg( \bf \: no.of \: images (n) = \frac{360}{ \theta} \bigg)$

★ Incase,

• completing the calculation using the above mentioned formula, If you get the answer in even terms you have to subtract 1 from the final answer to make it odd.

★ Here,

• θ = 45°

★ Substituting we get,

$\longrightarrow \tt \: n = \frac{360}{ \theta} \\ \\ \\ \longrightarrow \tt \: n = \cancel \frac{360}{45} \\ \\ \\ \longrightarrow \tt \: n = \cancel \frac{40}{5} \: \\ \\ \\ \longrightarrow \tt \: n = { \underline{ \boxed{ \frak{8}}}} \: \:$

• As the final answer is in even terms let's subtract 1 from it

$\longrightarrow \tt \: n = 8 - 1 \\ \\ \\ \longrightarrow \tt \: {\tt{\pink{ \underline{ \boxed{ \frak{n = 7}}}} \star}} \: \: \:$

• Henceforth, 7 Images are formed
