(1) The critical angles for the fused quartz is 44⁰,
(2) The critical angles for the polystyrene is 39⁰.
(3) The critical angles for the sodium chloride is 41⁰.
<h3>What is Critical angles?</h3>In optics, the critical angle is the topmost angle at which a shaft of light traveling in one transparent medium can strike the boundary between that medium and another with a lower refractive indicator without being fully reflected within the first
Critical angles for the different medium.
θ
where;
is the refractive index of air = 1
is the refractive index of the given substances.
Refractive index of quartz glass = 1.46
Refractive index of polystyrene = 1.59
Refractive index of sodium chloride = 1.54
Critical angles for quartz glass:
Critical angles for polystyrene
Critical angles for Sodium Chloride
Thus, the critical angles for the quartz glass is 44⁰, the critical angles for the polystyrene is 39 ⁰ and the critical angles for the sodium chloride is 41⁰.
