White light whose components have wavelengths from 400 nm to 700 nm illuminates a diffraction grating with 4000 lines/cm. Do the first-and second-order spectra overlap? Justify your answer.
Answer to relevant QuestionsShow that for a diffraction grating, the violet (λ = 400 nm) portion of the third-order maximum over-laps the yellow-orange (λ = 600 nm) portion of the second-order maximum, regardless of the grating’s spacing. In a double-slit experiment that uses monochromatic light, the angular separation between the central maxi-mum and the second-order maximum is 0.16o. What is the wavelength of the light if the distance between the slits is ...Sunlight is reflected off a vertical plate-glass window (n = 1.55). What would the Sun’s altitude (angle above the horizon) have to be for the reflected light to be completely polarized? Show that when the reflected light is completely polarized, the sum of the angle of incidence and the angle of refraction is equal to 90o. In order to observe fine details of small objects in a microscope, should you use blue light or red light?
