The spacing of ruled lines on a diffraction grating is 1,596 nm. The grating is
illuminated at normal incidence with a parallel beam of white light in the 392.0
nm to 700 nm wavelength band. The angular width of the gap between the first
order spectrum and the second order spectrum is closest to (in degree):

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
