Question

Why do distant object appear to be smaller and closer to each other?

Answer 1

Answer:

Because of the reduction in the visual angle.

Explanation:

The visual angle is that angle which is formed between the eye of the observer and the object which is being observed.

When the visual angle is greater, the object appears to be large and when the visual angle is smaller, the object appears to be smaller.

With the increase in distance, the visual angle decreases and with it decreases the size of the object.
