hkushwaha129p8pqot: Two plane mirrors are inclined at an angle. On one of those mirrors, the incident light rays run parallel to the other and if it first gets reflected and falls on the other mirror and makes an angle of 50 degree, then what will be the angle between the two mirrors ?
hkushwaha129p8pqot: here the question in English now pls try
RishabhRoy2002: 60°?

Ajayprajapati111: btw you answered well . i appreciate you but your diagram is little confusing because your your final ray got refracted instead of reflection
RishabhRoy2002: no it's for convince....the light is transversal... so i extended it
Ajayprajapati111: i know that fact men . but here reflection dominates so you have to show the final ray
RishabhRoy2002: Leave it na...
RishabhRoy2002: LOL
Ajayprajapati111: sorry no more comment. notification aa raha hai baar baar
hkushwaha129p8pqot: Your exterior triangle is little confusing
hkushwaha129p8pqot: Sorry it's not triangle if angle
hkushwaha129p8pqot: it
hkushwaha129p8pqot: Because exterior angle is full angle of outside and you don't added 20 degree so I will confusing
