Question
A convex mirror, like the passenger-side mirror on a car has a focal length of 1.00 m An object is 4.00 m from the mirror. You will have ONE SUBMISSION ONLY for the next two questions. It is a good idea to use a ray diagram to answer the first questions. You might also do the calculation to see that it is consistent with your drawing.

It is a good idea to use a ray diagram to answer the first questions. You might also do the calculation to see that it is consistent with your drawing (a) The image will be Select (b) The image will be -Select You will have FIVE SUBMISSIONS for the remaining parts. () Calculate the image distance, s' (d) Calculate the magnification, m.Explanation / Answer
using equation
1 / f = 1 / do + 1 / di
1/1 = 1 / 4 + 1/ di
1/ di = - 0.25 + 1
1/ di = 0.75
di = 1.333 m
since it is positive so image is infront of the mirror.
so image is real image.
Magnification
M = - di / do
= - 1.333 / 4
M = - 0.33325
so here it is negative, then it can say inverted
