Answer 1

The for total internal critical angle sing reflection -) sin 41 1 im 1.52 1 Sin 41° 0.656 A) By Law'- Snell's n, sino = n, sing, > 1.52 Sin (31.5) = (1) sina sing, 0.79419 O2 52.578° Answer all By Sneli's msino = Law n, sing - 1 sin 31.5° - 1.52 Sin sino, Sin315 ΤΩΣ 0.3437 --, 20-105 Answer
