A ray of light impinges from air onto a block of ice (n = 1.309) at a 33.0

Expert Solution

According to Snell'slaw refractiveindex n = sin?₁ / sin ?₂

forice n = 1.309

=> sin 33⁰ /sin ?_2,ice= 1.309

sin ?_2,ice= 0.416

?_2,ice= sin^-1(0.416)

= 24.59⁰

Similarily sin33⁰ / sin?_2,water= 1.333

sin?_2,water= 0.409

?_2,water= sin^-1(0.409)

= 24.12⁰

?_2,ice- ?_2,water= 24.59 - 24.12

= 0.47⁰
