ans. (a)3 (b)5
please someone solve for me.

Answer 1

hiii!!!

here's ur answer...

$number \: of \: images \: formed \: = \frac{360}{q} - 1 \\ \\ q \: is \: the \: divisor \: of \: 360 \\ \\ 1. \: angle \: between \: the \: plane \: mirror \: \\ is \: 90 \\ \\ therefore \: number \: of \: images \: formed \\ \\ = \frac{360}{90} - 1 \\ \\ = 4 - 1 \\ \\ = 3 \\ \\ hence \: 3 \: images \: will \: be \: formed. \\ \\ 2. \: angle \: between \: them \: is \: 60 \\ \\ therefore \: number \: of \: images \: will \: be \: formed \\ \\ = \frac{360}{60} - 1 \\ \\ = 6 - 1 \\ \\ = 5 \\ \\ hence \: 5 \: images \: will \: be \: formed. \\ \\ hope \: this \: helps \: you...$
