Question

Without calculations, sort the indices of the four materials. Justify your response.

Part 4. Sorting Refractive Indices of Several Materials Material Water (W) Pyrex Glass (PG) Silicon (S) Diamond (D) Angle of refraction 35 30 10 20 02 Without Calculations, sort the refractive indices of the four materials. Justify your reasoning.

Answer 1

Let us assume the ray is coming from air,

no- Refractive Index of Water nge of silicon npg Refractive Index of Pyrex Glass noe Of Diamond. ir By enells law. Given Refraction Angie Doxo xsini nsins V na sinic constant. For all Here air na-Refractive index of i= Angle of incidence. material ( no I sins noa I - no al ང Sin 20 al npg nsal sin (35) sin (30) sin/10) sin (10) sin(20) sin(30) I sin (35) ng> no ク Dessinate > nw npg?

sinx is an increasing function,

If x>y then sinx>siny
