The signature of an unknown element has a unique green color (550nm) in its emission spectra. You grabbed 4 sets of diffraction grating that would let you see this color. As you shine a light towards the element and into the diffraction grating, the color you expected appears at an angle of 20°. If the color is from a second-order spectra, which one did you use? a. 620 slits/mm grating b. 311 slits/mm grating c. 207 slits/mm grating d. 155 slits/mm grating

Which of following statement regarding holography is incorrect? A. Unlike a photography, the holography records both amplitude and phase information of the imaged objects. B. An optical hologram is produced through two beam interference, while image is reconstructed through light diffraction. C. Since several types of holograms can be reconstructed using regular white light, these holograms can produce and show true color images. D. When reconstruction beam only illuminates a small section of a hologram, one can still see whole image of the recorded object with lower resolution.
