Best ResponseYou've already chosen the best response.1After the white light has passed through the prism you have a spectrum coming out of a different edge. Now you could superimpose a screen with a single slit over that spectrum, centering the slit on the color your want. Alternatively, you could use a filter (e.g., red tinted glass or cellophane) to select for one color.

Best ResponseYou've already chosen the best response.0I understand the slit thing, making the space too small for any other of the colors to come out, but I don't understand the filter. Could you explain a bit?

Best ResponseYou've already chosen the best response.1Notice the question doesn't say a single frequency, but just a single color. So the red filter in this diagram would work.

Best ResponseYou've already chosen the best response.1Do a google search of "red filter", and you'll see it's quite common in photography. You can also use filters of other colors.

Best ResponseYou've already chosen the best response.0Crud... I see now that it's common sense, I've been googling how the heck to get one color to come out of a spectrum by itself for almost an hour
