Question

Two kids are playing with two mirror strips. They are

trying to make multiple images of a ball placed between the

two mirrors .For that ,they have to arrange the mirror strips at

certain angles.They want to make 6, 9,10,12 and 15 images at

five different settings.Find out the angles between the mirror

strips and draw the corresponding diagram for each images.​

Answer 1

the angle between the two mirrors for each of the following desired settings is given below

Explanation

• the number of images that are to be formed is given by the formula of 360/n - 1, Where n is the number of images that are to be formed by the plane mirror. if we consider the number of images formed equal to X, 360/(x+1) = n

1. So in order to form 6 images : 360/ (6+1)= 51.42°
2. so in order to form 9 images :360/ (9+1)= 36°
3. So in order to form 10 images :360/ (10+1)= 32.72°
4. So in order to form 12 images :360/ (12+1)= 27.69°
5. so in order to form 15 images: 360/ (15+1)= 22.5°
