What is the critical angle if a ray of light in Sodium Chloride (n=1.54) is headed into Quartz (n=1.46)?0.649⁰0.948°71.4°40.5°

Respuesta :

We can find the critical angle as follows:

[tex]\begin{gathered} \theta_c=sin^{-1}(\frac{n2}{n1}) \\ \theta_c=sin^{-1}(\frac{1.46}{1.54}) \\ \theta_c\approx71.4 \end{gathered}[/tex]

Answer:

71.4⁰
