Question
1. If f is negative for a convex mirror, what must di always be? What kind of image is this? What orientation will the image be? What will be the sign of the magnification? Will this ever be different for a convex mirror?
2. a. Now think about a concave mirror. Use the Mirror Equation to determine where the object is when the image changes from real to virtual.
b. Where is the object located if the image is half the size of the object? What is the orientation of the image?
c. Using the equation, discuss what happens to the image position, size and orientation as the object distance goes to infinity.
d. Using the equation, discuss what happens to the image position, size and orientation as the object moves from just inside the focal point to the vertex of the lens.
Explanation / Answer
The image distance is always negative for a convex mirror.
Since the image distance is negative, the image produced is a virtual image.
A virtual image is always upright
The sign of the magnification is positive
No for every convex mirror all the properties are same
