3. Categorize each statement as true or false. TrueFalse as the fringe order increase for a diffraction grating the fringe brightness decreases

True

Explanation:

According to the given situation, the statement is correct as it is secondary maxima of declining strength in the diffraction pattern.

Therefore, the fringe brightness decreases, the fringe order increase for a diffraction grating. So, the right answer is true.

So from the above explanation, the given statement is true

your answer is, orbit around the nucleus
