Why does a gas discharge tube have a certain color? O (d) The tungsten filament of the tube glows O (c) The gas radiates only a few discrete wavelengths O (f) None of the choices provided. (b) The discharge tube is surrounded by a color filter O (e) The color depends on the temperature of the gas with hotter gases being more blue. (a) The gas radiates a continuous spectrumBlue light is bent more by a glass prism than orange light. This is because O (d) blue light has a lower index of reflection than orange light O (f) blue light is bent less by a prism than orange light O (c) blue light has a lower index of dffraction than orange light O (b) blue light has a higher index of refraction than orange light O (e) blue light has a lower index of refraction than orange light O (a) blue light has a higher index of reflection than orange lightIn the lab on lenses, the lab manual describes how to construct a microscope. What is the proper way to arrange the equipment? O (b) lamp, lit object, longer focal length lens, shorter focal length lens, eye O (f) laser, longer focal length lens, shorter focal length lens, photometer O (d) lamp, lit object, shorter focal length lens, longer focal length, eye O (a) lamp, longer focal length lens, shorter focal length lens, eye (e) lit object, shorter focal length lens, eye (c) lit object, longer focal length lens, paper screen
