Q. Light traveling from water to air undergoes TIR when

पानी से हवा में यात्रा करने वाला प्रकाश TIR से गुजरता है

A
Incidence angle < critical angle
आपतन कोण < क्रांतिक कोण
B
Refractive index of air > water
वायु > जल का अपवर्तनांक
C
Incidence angle > critical angle
आपतन कोण > क्रांतिक कोण
D
Incidence angle = 0
आपतन कोण = 0

Explanation

Total internal reflection in water-air boundary occurs only if the angle of incidence inside water is greater than the critical angle (~49° for water-air interface).

जल-वायु सीमा में पूर्ण आंतरिक परावर्तन केवल तभी होता है जब जल के अंदर आपतन कोण क्रांतिक कोण (जल-वायु इंटरफेस के लिए ~ 49°) से अधिक होता है।
