Do two light waves with difference frequencies connect when they meet?

[QUOTE="Ibix, post: 6384203, member: 365269"] Filters block specific frequencies. If you have light that is a mix of two frequencies, one of which is absorbed by the filter and the other of which is transmitted then you will get one of the frequencies transmitted and one absorbed. What happens in your example depends on what you mean by "blue light", "green light" and a "green color blocker". If your light is a mix of two monochromatic sources, say 400nm (typical blue) and 550nm (typical green), and your filter absorbs wavelengths between 500 and 600nm and nothing else then the green component will be absorbed and the blue component passed. But a "green color blocker" might absorb some frequencies you'd call blue - so you need to specify exactly what light and what filter you have if you want an unequivocal answer. [/QUOTE]
