Question 1

An optical fiber transmits light efficiently based on the principle of Total Internal Reflection (TIR). Which of the following conditions is most essential for TIR to occur when light travels from the core (denser medium) to the cladding (rarer medium) of an optical fiber?

Accepted Answer

C. The angle of incidence must be greater than the critical angle. — Total Internal Reflection (TIR) occurs when two conditions are met: first, light must travel from an optically denser medium to an optically rarer medium. Second, the angle of incidence in the denser medium must be greater than the critical angle. If the angle of incidence is less than the critical angle, refraction will occur, and light will pass into the rarer medium. The angle of refraction being 90 degrees defines the critical angle itself, not the condition for TIR.

Answer

A. The angle of incidence must be less than the critical angle.

Answer

B. The angle of refraction must be exactly 90 degrees.

Answer

D. The refractive index of the cladding must be greater than that of the core.

Accepted Answer

C. Contextual intelligence — Sternberg's Triarchic Theory defines contextual (practical) intelligence as the ability to adapt to, shape, or select environments, often referred to as 'street smarts.' This involves practical problem-solving, negotiation, and adapting to real-world situations, which aligns perfectly with the entrepreneur's described abilities. Componential (analytical) intelligence focuses on academic problem-solving, experiential (creative) intelligence on novel ideas, and linguistic intelligence is a concept from Gardner's theory.
