(2) how does the image formed in a pinhole camera change when the hole is enlarged??? explain ​

Answer 1

Answer:

1-->root, in botany, that part of a vascular plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.

2-->If the size of the hole in a pinhole camera is as big as the size of a green gram then the sharpness in the image decreases. The image becomes thick and the image is a blur. If the size of the hole of a pinhole camera increases then more light enters and disturbs the formation of the image.
