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.

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

@BetterContentConsumption-qc3hb Ай бұрын

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

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.

@Shivkumar-pg1yw 8 ай бұрын

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.

@parraytowfeeq4746 4 ай бұрын

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 3 күн бұрын

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!

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
