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

@AnkitAgrahari-mm9rm 9 месяцев назад

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

@ashwinin4983 9 месяцев назад

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

@ManochaAcademy 9 месяцев назад

Correct!!

@assassin4737 3 месяца назад

@@ManochaAcademy but something/0 is not defined. So more accurate would be not defined?

@BetterContentConsumption-qc3hb Месяц назад

Something / 0 does not give a fixed value as the result of the operation, but the fact remains that the value we obtain will be extremely large (this can be predicted by substituting 0 by numbers close to 0 such as 0.1, 0.01, .... and so on. In short, no matter the value, it will be extremely large i.e. infinity, what is not defined is something like 0/0

@user-md4sf6jp7d 9 месяцев назад

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❤

@sriritwikshastry9603 9 месяцев назад

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 :)

@ManochaAcademy 9 месяцев назад

Thanks! Super correct answer

@parraytowfeeq4746 5 месяцев назад

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. .....is it correct sir ??

@EmpyreanLightASMR 24 дня назад

I think that's correct. If you draw the ray traces on paper, for example for 120° inclined mirrors, the object symmetrically will be 2 images. 360/120 - 1 = 2. but if you keep following the reflections, you'll see a 3rd image forming in the distance behind the mirrors, which isnt visible until the object is moved off the bisector. I do not know if the width/thickness of the object affects this. I would need real mirrors to try it out!

@Ayush_Chatterjee 9 месяцев назад

Very helpful, Sir.😊😊

@Arikstudent 8 месяцев назад

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

@ThrillingRide-OP 9 месяцев назад

@qwerty-wf8rd 7 месяцев назад

THANKU SO MUCH SIR FOR THIS WONDERFUL EXPLANATION

@EmpyreanLightASMR 24 дня назад

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.

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

@bobbydazzler8794 14 дней назад

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

@user-pp4wp5yu8m 5 месяцев назад

The images formed by an object placed btwn 2 parallel mirrors will be 2 I think it's becoz the object will be obstructing reflection from either images formed to reach the other mirror. Am I right? please I need to know?

Hello sir.. I love your teaching techniques and it amazes me how a person can be good at Science, Mathematics,computer and for that matter even English at the same time😊.Your videos on physics, chemistry and computer help me a lot with my studies.Initially,I used to find computer applications to be boring,but now, after watching your videos,I find it to be a very interesting subject😊. Could you please tell me the difference between acceleration and speed as I am slightly confused.Please reply to my comment. Yours Archita

@ManochaAcademy 9 месяцев назад

Hi Archita, great to know that you like our videos and you are liking the computer videos as well. Do check out our video on speed velocity and acceleration. You can search on RU-vid for that.

@robbienoel1146 13 дней назад

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

@sonalmathur6448 9 месяцев назад

Sir, in the case of 2 parallel mirrors, the images formed are infinite.

@ManochaAcademy 9 месяцев назад

Right answer

@Shivkumar-pg1yw 9 месяцев назад

When an object is kept between two parellel plane mirrors facing each other i.e 0°, infinite number of images will be seen. THEORITICALLY IT IS TRUE BUT IN ACTUAL PRACTISE ONLY A LIMITED NUMBER OF IMAGES ARE FORMED. THIS INFINITE IMAGES IS BECAUSE SOME LIGHT GETS ABSORBED BY THE MIRRORS DURING EACH REFLECTION. THE IMAGES ARE SO SMALL THAT WE ARE NOT ABLE TO SEE IT.

@raagmuz 9 месяцев назад

Infinite images will be formed as the angle between the two mirrors in infinity and infinity - 1 = infinity

@ManochaAcademy 9 месяцев назад

Super! Right answer!

@vivek12849 7 месяцев назад

we know n=360°/θ ★if we place mirror parallel then angle between mirror 🪞 is zero therefore n=360°/0 n= ∞ now (n-1) (∞-1) = ∞✓✓✓✓
