A polymer coating has a n=1.30 and a base of n=1.50. What is the minimum thickness of the coating to reflect 500 nm least strongly?
Click For Summary
SUMMARY
The discussion focuses on calculating the minimum thickness of a polymer coating with a refractive index of n=1.30, applied over a base with a refractive index of n=1.50, to achieve minimal reflection at a wavelength of 500 nm. The solution involves applying the principles of thin-film interference, specifically the condition for destructive interference. The minimum thickness can be determined using the formula for thin films, which requires the wavelength in the medium and the refractive indices of both layers.
