Question

n= 360/a-1
What is this formula used for? Need this answer urgently​

Answer 1

Explanation:

The formula for finding this is : - n=360/x or n=360/x - 1, where n is the no. of images, x is the angle of inclination between the two mirrors & n is always an odd integer.

For example: if the angle between the two mirrors is 30 degrees, n=360/30 - 1= 12-1 = 11

Answer 2

Answer:

finding of images formed

Explanation:

The formula for finding this is : - n=360/x or n=360/x - 1, where n is the no. of images, x is the angle of inclination between the two mirrors & n is always an odd integer.

For example: if the angle between the two mirrors is 90 degrees, n=360/90 - 1= 4-1 = 3
