Q TO GET NINE IMAGES OF A SINGLE OBJECT,WHEN PLACED ASYYMETRICAL BETWEEN TWO PLANE MIRRORS.ANGLE BETWWEN 2 PLANE MIRRORS SHOULD BE.

Open in App

Solution

f two plane mirrors are placed at an angle θ.
Number of images formed = (360/θ) - 1=9

θ=360/(9+1) =36 degree

Hence angle=36 degree

Hope it was helpful :)

Q. An object is placed (1) asymmetrically (2) symmetrically, between two plane mirrors inclined at an angle of 50°. Find the number of images formed

Q. Assertion: If the angle between the two plane mirrors is

72^{\circ}

and the object is asymmetrically placed between the two mirrors, then

5

images of the object will be formed.
Reason: For a given system of mirrors, the total number of images formed due to successive reflection of an asymmetrically placed object is equal to either

\frac{360^{\circ}}{θ}

\frac{360^{\circ}}{θ} - 1

\frac{360^{\circ}}{θ}

is odd or even respectively.
