Question

White light is a combination of visible light ranging from blue at a wavelength of around 400 nm to red at a wavelength of about 700 nm. For white light shown through a diffraction grating of 1000 slits/cm onto a screen 15 cm behind the grating, 

(a) Draw the zeroth order bright spot(s)

(b) Draw the first order bright spot(s)
