← ScienceWhich consequence results when total internal reflection fails?
A)Signal loss within optical fiber✓
B)Refraction reaches Brewster's angle
C)Diffraction cancels wavelength components
D)Amplification increases evanescent waves
💡 Explanation
If the angle of incidence is insufficient, total internal reflection ceases, because the angle of incidence does not exceed the critical angle; therefore, light exits the dielectric rather than remaining contained for data transmission.
