Homework Help Overview

The discussion revolves around the formation of images when a man is viewed in the corner of two mirrors positioned at right angles. Participants explore how many images are created and the orientation of the man’s hands in these reflections.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the number of images formed and the conditions under which the man is viewed. Questions arise about the man's orientation relative to the mirrors and the implications for which hand is visible in the reflections.

Discussion Status

There is an ongoing exploration of the problem with participants sketching layouts and questioning assumptions about the man's position. Some guidance has been offered regarding the interpretation of the images, but no consensus has been reached on the visibility of the right hand.

Contextual Notes

Participants note that the problem does not specify the man's orientation, leading to various interpretations. The discussion includes references to common experiences with mirrors in elevators, suggesting familiarity with the topic.

The Attempt at a Solution

There will be 3 images formed .If the man is standing symmetrically then first image will be behind mirror M1 .2nd will be behind M2 . 3rd will lie on the angle bisector of the mirrors .This image will be behind both M1 and M2 .

Now I don't think in any of the images , the man will be seen using his right hand .He will be seen combing with his left hand .But this is incorrect answer .

What is the mistake?

Try sketching the layout. What will this image look like?

Have you ever looked into the corner of two mirrors at right-angles? Its a reasonably common find in elevators.

Do we assume man to be facing one of the mirrors Or Is he facing the corner of the mirrors ?

No . Never had the opportunity to look in right angled mirrors .

It simply says 'how many images will be seen'. i.e. no assumptions need be made.

BTW, you noted that yourself in your answer: 3 images will be seen.

Pretend you are hovering over the man's head. Sketch the diagram of the images:

From your posts it seems that this 3rd image behind the corner is the one where the man is seen using the right hand . Is that the case ?

I am not saying that at all.

I provided a sketch for you to mark up.
