Question

An object is placed asymmetrically between two plane mirrors at an angle of 45 degree . How many images are formed?​

Answer 1

Answer:

Explanation:

For two mirrors kept at an angle x, the number of images n is determined by the formula 360/x.

If n turns out to be odd,

We have the following two cases:

Asymmetrically

--------------------

Number of images=n

Symmetrically

------------------

Number of images=n-1

And if n turns out to be even,

Number of images= n-1 for all positions of object

Now, coming back to your question,  

Here x=50

n=360/x

 =360/50

 =7.2

Rounding off,n=7

Now,n is odd.

(1) Asymmetrically

number of images=n

                            =7

(2) Symmetrically

number of images= n-1

                           = 7-1

                           =6

Answer 2

Answer:

hlo

Explanation:

Correct option is

D

(1)7, (ii)6

Case (a):

Two plane mirrors places asymmetrically at 50 degrees.

Number of images =

50

360

=7 (highest integral value)

Case (b):

Two plane mirrors places symmetrically at 50 degrees.

Number of images =

50

360

−1=6 (highest integral value)
