. Two plane mirrors are placed making an angle 6° in
between them. For an object placed in between the
mirrors, if angle is gradually increased from 0° to 180°,
how will the number of images change: increase,
decrease or remain unchanged ?​

Answer 1

Answer:

decrease

Explanation:

no of image =(360/ø)-1 (if 360/ø is even)

or simply 360/ø (if its odd)

ø is thieta here

so if ø will increase, i.e.,angle will increase then no of image will decrease
