Question

In the diffraction grating equation, d sin θn = nλ, what does the symbol 'd' represent?
Options
A The wavelength of the incident light.
B The angle of deviation for the nth bright fringe.
C The order number of the bright fringe.
D The spacing between adjacent slits on the grating.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

On page 6, the text explicitly states 'where d=spacing of slits' directly below the grating equation d sin θn = nλ.

Hint

Refer to the definition of terms immediately following the diffraction grating equation on page 6.
