Question

If the angle between two mirrors is 90°, the number of images formed will be. ​

Answer 1

Answer:

3

Explanation:

USE FORMULA :-

(360/θ) - 1

where θ is the angle between two mirrors .

(360/θ) - 1 = (360/90)-1 = 4-1 = 3

Answer 2

Answer:

3 image will be formed.

Explanation:

no. of image = 360°÷given angle -1 (only for even no. of mirror).

360°÷90°-1 = 4 - 1= 3

note:- no. of image = 360°- given angle ( for odd no. of mirror)
