White light consisting of wavelengths ranging from 400nm to 700 nm fall incident upon a diffraction grating having 600 lines/mm. The first order spectrum extends over a range of angles on a screen. Next, the grating is removed and replaced with one having 900 lines/mm. Which of the following statements are correct about the range of angles comprising the first order spectrum?
