Question

if two plane mirror kept at 30degree celsius angle then number of images formed (a)8(b)9 (c) 10 (d) 11​

Answer 1

Answer:

11 images

n = ( 360 / theta ) - 1

So, here, we have the mirrors placed perpendicular to each other. So, theta = 90 degree

=> n = no. of images formed

=> n = ( 360 / 30 ) - 1

=> n = 12 - 1

=> n = 11

So, a total of eleven images will be formed.
