Question

estimate the number of images produced if a tiny object is kept in between two plane mirrors inclined at 35 degree,36 degree,40 degree and 45 degree​

Answer 1

Answer:

The Number of Images Produced are as follows:

Explanation:

The Number of Images formed in two plane mirrors inclined at an angle A to each other is given by the formula:

            Number of images = (360/A)-1

(a) At 35⁰

$Number \ of \ images=(\frac{360}{35})-1\\ =9.28 ~ 9 images$

(b) At 36⁰

$Number \ of \ images=(\frac{360}{36}){-1}\\=10-1\\=9$

(a) At 40⁰

$Number \ of \ images=(\frac{360}{40}){-1}\\=9-1\\=8$

(a) At 45⁰

$Number \ of \ images=(\frac{360}{45}){-1}\\=8-1\\=7$

Answer 2

Explanation:

n= number of images

At 35

$n=\frac{360}{35} -1\\  =10.28-1\\n=9.28$

At 36

$n=\frac{360}{36}-1\\  =10-1\\n=9$

At 40

$n=\frac{360}{40}-1   =9-1\\n=8$

At 45

$n=\frac{360}{45} -1\\  =8-1\\n=7$
