Question

question 4
when light rays from a distant star pass through a lens they converge at a single point called the _______. 1 pts
resolution
grazing incidence
diffraction limit
focus
pixel

Explanation:

In optics, when light rays pass through a lens and converge at a single point, that point is known as the focus. Resolution refers to the ability to distinguish details, grazing incidence is about the angle of light - surface interaction, diffraction limit is related to the wave - like behavior of light and the smallest detail that can be resolved, and a pixel is a unit in digital imaging.

Answer:

E. focus
