Solution Summary
The expert examines light wavelengths in a slit experiment.
Solution Preview
There's one simple equation to use for this problem.
Wavelength = (distance between bright lines x distance between slits) / distance from slits to screen.
So what information do we have?
Distance between bright lines (w) = 21.1mm
Distance between slits (s) = 0.019mm
Distance from slits ...
