The rhinestones in costume jewelry are glass with index of refraction 1.50. To make them more reflective, they are often coated

Answer:

$T=62.9*10^{-9}$

Explanation:

From the question we are told that:

Index of refraction of Rinestones $\gamma_1 =1.5$

Index of refraction of silicon $\gamma_2 =2.0$

Wavelength $\lambda=576nm=576*10^{-9}$

Let each layer have thickness T

Therefore

Total Thickness =2T

Generally the equation for Constructive interference is mathematically given by

$2T=(m+0.5)\frac{l\lambda}{\gamma_2}$

Where

$M=0$

$2T=(0+0.5)\frac{576*10^{-9}}{2*2.0}$

$T=62.9*10^{-9}$
