Question

Suppose you have two small photographs of the Moon. Although both look the same at small size, when you blow them up to poster size one of them still looks sharp while the other one becomes fuzzy (grainy) looking. Which of the following statements is true?

a. Both photographs have the same angular resolution, because they are both photographs of the same object
b. The one that looks sharp at large size has better (smaller) angular resolution than the one that looks fuzzy
c. The one that looks fuzzy at large size has better angular resolution (smaller) than the one that looks sharp
d. Both photographs have the same angular resolution, because they were both printed at the same sizes in each case

Answer 1

The correct option to answer your question will be option "b" the one that looks sharp at large size has better (smaller) angular resolution than the one that looks fuzzy.

Step-by-step explanation:

The angular resolution is defined as the capacity of any capturing device like a camera, microscope, telescope to distinguish small details of an object. The picture that looks fuzzy when the size is increased to poster size, is the one with less angular resolution and therefore if the size is increased the picture will be fuzzy.
