When object is kept between two plane mirrors
making certain angle, 5 images are formed.
What is the measure of an angle between the
plane mirrors?
Need Answer with proper explanation..
Answers
Answer:
Explanation:
Use the formula
Y = 360/x
where x = angle between the mirror
y = no. of images
if the object is placed symmetric to both the mirrors, subtract 1 from Y because the two formed images overlap on each other.
For unsymmetrical placement of object, Y is the answer.
For your case,
Symmetric placement, Y = 360/75 - 1 = 3 (complete images)
unsymmetric placement, Y = 4
The value 0.8 represents an incomplete image.

360/75 = 4.8 say 4.
So the numbers of images will be 4–1 = 3.

Answer:
Angle measured is 60°
Explanation:
The number of images formed when two mirrors are placed at an angle theta to each other is given by: n = ( 360 / theta ) - 1.
Here, n = 5, so ( 360 / theta ) = n+1 = 6, hence theta = 360/6 = 60 deg.
So the mirrors are placed at an angle of 60 deg with each other.
