A rhinestone is made of flint glass with an index of refraction of 1.50. To make it more reflective, it is coated with a thin film of Si0 that has a refractive index of 2.00. Find the first two possible thicknesses of the SiO coating that provide strong reflection for 570 nm light at normal incidence.

The answer that would best complete the given statement above would be the term SUPERPOSITION. Here is the complete statement. When two waves meet they combine according to the superposition principle. Hope this answers your question. Have a great day ahead!
