Question
Poke a pinhole in a piece of card and hold it in sunlight and an image of the Sun is cast on the floor. The Sun-image diameter depends on the height of the pinhole above the floor. Measurements for all heights show the Sun-image diameter is about 1/100 the distance between the pinhole and the floor. This means thatA) about 100 end-to-end Sun images would fit between the pinhole and the floor.
B) distance-wise, the Sun is about 100 Suns away from Earth.
C) both of these
D) none of the above
