Number of Images formed by Two Plane Mirrors

Number of Images formed by Two Mirrors

The formula to calculate the number of images formed by two plane mirrors facing each other is:
Number of Images = (360 degrees / Angle of inclination between the mirrors) - 1

In this formula: "Angle of inclination between the mirrors" refers to the angle between the two mirrors. This angle is measured between the normals (perpendicular lines) to the mirror surfaces. If the mirrors are parallel, the angle of inclination is 0 degrees.

The "-1" at the end of the formula is used to account for the original object, so you subtract 1 from the total number of images to get the count of additional images formed by the mirrors.

This formula assumes ideal conditions with perfect mirrors and no distortions. In practice, the actual number of images may vary due to imperfections in the mirrors and the angle of inclination.

I would say, if two mirrors are placed parallel to each other, the angle becomes 0 and the formula that you told us is n=(360/theta)-1, nevertheless, in this case theta is 0 and it seems undefined. But when I try this, there are images that are formed and it dawns on me that this is a kind of problem that CALCULUS solves. Therefore, as the angles APPROACHES to 0, the number of images formed
Is gonna be INFINITY. The answer is INFINITY.
THANKS FOR THIS MIND BLOWING QUERY.

Ive started watching your videos since 2 months. You made physics so easy and crystal clear for me . Thank you sir

7:48 this works for the 90° mirrors, but when I draw the rays for mirrors inclined at 120°, I get a 3rd (hidden) image, which should appear if the object is moved off the bisector—so slightly asymmetrical to the mirrors. And that third reflection is way far away! Anyway, hopefully I did it all correctly.

[AnkitAgrahari-mmrm]

Infinite images will form in that case.
Explanation was wonderful👍

[ashwinin]

Infinite images will be formed. 2 green circles will be formed which are concentric in both the mirrors

[ThrillingRide-OP]

Sir please keep making videos on class 10 science

[sriritwikshastry]

Such an amazing video sir! Loved it!
If the mirrors are placed in front of each other there will be infinite images... We can see this in the barber shops too :)

[Arikstudent]

Can you explain why there will be infinite images???
Is it because thithas value is 0
In real life using this we can see the bck of the object

[robbienoel]

I would say the only thing wrong with the logic between the dice is with your math where you rounded down or got rid of the decimal

I Would be only rounding down to wholes or .5 because the dice themselves can replace halves and or wholes with the mirrors colliding

[EmmanuellaOnyebuchi-uk]

Object is at infinity
I HV been enjoying your classes thank u cause I HV really improved in some aspects and hope to improve more❤

[BakaMemes]

360/0=undefined(Since they are parallel the angle is 0), Therefore the object is at infinity

[starkYT]

If the mirror are the place in front of each other there will be infinite images .
For example : we can see this in the barber shops

Sir how many numbers of reflections on each image form at a 90 degrees angle in the case of inclined mirrors?

[yashrajverma]

What will be the no. Of images formed when three mirror s are inclined to each other at 90* ?

[parraytowfeeq]

Sir one teacher said that if we find the no. of images and if we get the answer in even then we need to subtract 1 from the even no. Nd if we get the no. of images in odd so there are two cases if object is placed symmetrically then we need to subtract 1 and if obj is not symmetrically (asymmetrically) placed then there is no need to subtract 1 from the odd no. it correct sir ??

[Aarush_]

Sir, when we use the formula 360/angle, if we get the answer as an odd number we don't subtract 1 but if its even we subtract 1 right?? (My physics sir told this in school

[almisbah_channel_official]

Thank you manocha Acedmy for helping us in our study

[AnnuKasaudhan-myze]

The answer is Infinite images.
I experience this event when I go to cut my hair at haircutting shop which We say in own language "NAE KI DUKAN".
Thanks for your explanation.❤
