Question

Choose all that are correct about a diffraction grating.

Diffraction grating produces interference pattern only for transmitted light (light passes through), but does not work for reflected light (light reflected off the surface of the diffraction grating).

Diffraction angle will be different if the slit-to-slit distance of the diffraction grating is different.

If the size of the slit opeing of diffraction grating is much larger than the wavelength of light, the diffraction pattern becomes stronger (stronger contrast between maxima and minima).

For a given diffraction grating, the wavelength of an incident light can be determined from the diffraction angle

Explanation / Answer

(b)true because d(sin(theta) = (lambda)/2

(c)true

(d)true
