Question

What is the most likely outcome of increasing the number of slits per unit distance on a diffraction grating?1) lines become narrower2) distance between lines increases3) lines become thicker4) distance between lines decreases

Answer 1

It's important to know that diffraction gratings can be identified by the number of lines they have per centimeter. Often, more lines per centimeter is more useful because the images separation is greater when this happens. That is, the distance between lines increases.

Therefore, the answer is 2.
