Question

a) How did the image produced by the diverging mirror differ from that produced by the converging mirror? What sign convention must be used with hi if the magnification equations are to give consistent results?

b) The radius of curvature for a plane mirror is infinite. This means that 1 f   equals zero. What must be true about do and di if the mirror equation is to be true for flat mirrors? Where must the image always be? What must its magnification be?

c)The passenger side rear view mirrors on many cars are diverging rather than plane mirrors. What is the advantage of using a diverging mirror? What is a disadvantage?

Explanation / Answer

A:

for a converging lens, image can be caught on the screen as the rays are converging rays

but for a diverging lens, image cannot be caught of screen as this form a virtual image

we use - ve sign for diverging lens and +ve for converging lens

--------------------

B:

as if R = infinite, it means, mirror must be a plane mirror

magnification = 1

-------------
c. the advantage is the image apears closer than it appears and

disadvantage is in reverse the image
