Question
Two sources of light illuminate a double slit simultaneously.One has wavelength 560 nm and the second has an unknown wavelength. The m = 4 bright fringe ofthe unknown wavelength overlaps the m = 3 bright fringe of the light of 560 nm wavelength.What is the unknown wavelength? Two sources of light illuminate a double slit simultaneously.One has wavelength 560 nm and the second has an unknown wavelength. The m = 4 bright fringe ofthe unknown wavelength overlaps the m = 3 bright fringe of the light of 560 nm wavelength.What is the unknown wavelength?Explanation / Answer
dsin(theta) = m(lambda);
4*570nm=5*x;
x=456nm
