Light of wavelength 600 nm shines on a diffraction grating that has 400 lines per cm. The light emerging from the grating hits a screen 50 cm wide so that the central maximum is exactly in the middle of the screen. Assume that the screen is 3 m from the grating.

How many maxima appear on the screen?

(a)

4

(b)

6

(c)

7

(d)

5

(e)
