Consider this statement: Think of the reflection of the Moon on a cloudless night: Look in the ocean, you see a large moon. Look in a pond; the same moon is there. In a puddle, in a teacup-cverywhere, diminished somewhat in size, but all the features are there.

(a) What physical attribute (referred to only indirectly in the statement) is it that differs in size for the ocean, pond, puddle, and cup?

(b) What other quantity or quantities determine this attribute? Draw a diagram showing how the image of the Moon forms and relating all the quantities you've identified to one another.
