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.
