SUMMARY

The discussion focuses on determining the properties of an image formed by a concave mirror with a focal length of 50 cm, where the object is positioned 1.5 m away and is 2.5 cm tall. The mirror equation, defined as 1/image distance + 1/object distance = 1/focal length, and the magnification equation, m = image size / object size, are essential for solving this problem. Participants emphasize the importance of using a diagram to correctly apply the sign convention and suggest practical experimentation with a spoon to visualize image orientation.

PREREQUISITES
  • Understanding of the mirror equation
  • Familiarity with the magnification equation
  • Basic knowledge of concave mirrors

20. Using the mirror equation and the magnification equation, find the four properties of the image formed in a concave mirror with a focal length of 50 cm, if the object is 1.5 m from the mirror and is 2.5 cm high.


Can anyone tell me the mirror equation and magnification equation and how to apply to this problem please?... Thankyou

Mirror equation is
1/image distance + 1/object distance = 1/focal length

magnification equation is
m = image size / object size

Draw a diagram or you will never get the sign convention right - hint experiment with a spoon to work out which way up the image should be.
 
thankyou
