Plane Mirror and Light Rays

I had some questions about mirrors, please provide supporting equations and information for these problems.
- Does the mirror equation (p^-1 + d^-1 = 2R^-1 = f^1) apply to a plane mirror? What relationship between p and d does it imply?

- Why is it when you stand in front of a mirror your left appears on your right and your right on your left but you do not appear to be upside down?( or your top on the bottom, and the bottom on the top)

- A person spearfishing from a boat sees a fish that is 3 m from the boat at the depth of 1m. In order to spear the fish, should the person aim at, above, or below the image of the fish?

Does the mirror equation (p^-1 + d^-1 = 2R^-1 = f^1) apply to a plane mirror? What
relationship between p and d does it imply?

This equation is still valid in the case of a plane mirror. For a plane mirror, f and R are infinity and therefore p = -q. It means it is virtual image and the distance ...

Solution Summary

This solution uses the concepts of refraction index, plane mirror properties and real and image determination to answer the questions. Clear explanations are provided.
