Answer 1

Heya!!! Mate here is ur ans.......

On second mirror ray of light retraces its path

On second mirror ray of light retraces its path ⇒ ray of light falls normally on the second mirror

On second mirror ray of light retraces its path ⇒ ray of light falls normally on the second mirrori.e., b=90

On second mirror ray of light retraces its path ⇒ ray of light falls normally on the second mirrori.e., b=90a=90−r1 =60

On second mirror ray of light retraces its path ⇒ ray of light falls normally on the second mirrori.e., b=90a=90−r1 =60θ=180−(b+a)

On second mirror ray of light retraces its path ⇒ ray of light falls normally on the second mirrori.e., b=90a=90−r1 =60θ=180−(b+a)=30 degrees
