while tracing a path of ray of light passing through a rectangular glass slab a student tabulated his observations as given below:
1] angle i=60`,angle r=40`angle e=61`
2] angle i=50, angle r=36, angle e=51
3] angle i=40,angle r=28 ,angle e=39
4] angle i=30,angle r=20 ,angle e=31
from the above given options which is the correct bservation?? explain briefly

HELLO DEAR,angle i = 30 , angle r = 20 , angle e =31
refractive index of glass = 1.52
sin i / sin r = 1.52
sin 30 = 1.52 x sin r
0.5/1.52 = sin r
=> sin r = 0.32
=> r = 20(approx 19)
I HOPE ITS HELP YOU DEAR,
THANKS
