Ray Diagram for Concave Mirror: Image Position & Height

Click For Summary

Homework Help Overview

The discussion revolves around a problem involving a concave mirror, where participants are analyzing the image position and height based on a ray diagram. The original poster describes an object height and distance from the mirror, along with a radius of curvature.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the need for a drawn diagram to assess the original poster's measurements and reasoning. Questions arise regarding the interpretation of the measurements provided, particularly the significance of the 6 cm figure mentioned.

Discussion Status

The discussion is ongoing, with participants encouraging the original poster to provide a diagram for better clarity. There is an indication that some measurements may have been misinterpreted, but no consensus has been reached yet.

Contextual Notes

Participants note that the original poster's height measurement of the image appears to be incorrect, and there is confusion about the radius of curvature mentioned in the problem. The requirement to draw a diagram is emphasized as critical for further assistance.

A 1.0 cm high object is situated 11.0 cm in front of a concave mirror that has a radius of curvature of 8.00 cm. Using a ray diagram drawn to scale (the mirror must be drawn to scale):

(a) measure the location of the image:
6cm (infront of the mirror)

(b) measure the height of the image (and give its orientation).
? cm (inverted)

I drew a diagram and all, and got 0.5 cm for the height, but it was wrong...
Thanks

Em, if these involve direct measurements from the diagram, then there's no easy way to say this but you're going to have to attach your diagram somehow.
 
There is no diagram... You're suppose to draw it.

Yeah, I know, that why we'd like to see the one you've drawn because otherwise we can't see your attempt, and where you may gone wrong (if you've gone wrong textbooks can be wrong you know:smile:)
 
Ok, I'll try my best to redraw it and post it in a second.

It's not going to be very easy at all for anyone to help you on this one! One thing I would note is the number in the box on the right (6cm). What does that denote? Is it the radius of curvature of the mirror? If so, this should be 8cm (as stated in the question).
