Ray Refracted into Medium 2
θ₁ (from Normal): 0.0°
θ₂ (from Normal): 0.0°
CRITICAL ANGLE REACHED (θ₂ = 90.0° from Normal)!
Drag red laser source in Medium 1 to change angle of incidence θ₁

Analyze ray behavior & verify if Critical Angle is possible
Instructions: Drag the laser in Medium 1 from 0° to 90°. Observe how the refracted angle θ₂ changes relative to the vertical Normal line. Determine if a critical angle ($\theta_2 = 90^\circ$) exists for this medium pair!
