The phenomenon of total internal reflection is observed for an angle of incidence ______?
کل داخلی عکاسی کا رجحان واقعات کے زاویہ کے لئے مشاہدہ کیا جاتا ہے؟
Answer: Greater than critical angle
Explanation
Total internal reflection occurs when light travels from a denser to a rarer medium, and the angle of incidence exceeds the critical angle.
At this point, light is completely reflected back into the denser medium.
