Digital Photography and Math?

A low-resolution digital photographs use 262,144 pixels in a 512 x 512 grid. If you enlarge a low-resolution digital photograph enough, describe what will happen.

Answers:

1The total number of pixels will remain the same, but will now be spread out over a larger area.

Let's say the initial photo was 1 inch by 1 inch, that means the original resolution was 512 dpi (dots per inch).
If you enlarge it to 2 inches by 2 inches, you still have 512 x 512 pixels, but now over 2 inches. The resolution drops to
206 dpi.

This is why it gets blurry as you enlarge it.
