Is the object and image at the same distance from the plane mirror?

• Yes

• No

• Maybe

Is the object and image at the same distance from the convex mirror in the above picture?

• Yes, because the number of squares is equal

• can't say, the size of the squares is not equal.

The object that is closer to the observer is going to have a ____ ___ ______ compared to an object that is farther

• larger shift in its position
