प्रश्न

An object is placed (i) asymmetrically (ii) symmetrically, between two plane mirrors inclined at an angle of 50°. Find the number of images formed.

बेरीज

उत्तर

Angle between the mirrors, θ = 50o

Now, n = 360o / θo = 360o / 50= 7.2  7, which is odd.

(i) When placed asymmetrically, number of images formed will be n, i.e. 7.

(ii) When placed symmetrically, number of images formed will be (n-1); i.e. 7-1 = 6 images
