Question 4

Before introducing a complex unit on the human circulatory system, a biology teacher begins the lesson by presenting a brief overview of how different body systems work together to maintain life, and then specifically highlights the general function of transportation within the body. This approach is most consistent with which of David Ausubel's principles of meaningful learning?

Accepted Answer

C. Advance organizers — Ausubel's theory of meaningful verbal learning emphasizes the use of advance organizers, which are introductory materials presented before new learning material. Their purpose is to provide a conceptual framework or overview that helps learners connect new information to their existing cognitive structure. Subsumption is the process of integrating new information, while rote learning is the opposite of meaningful learning, and discovery learning is a concept by Bruner.

Question 7

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.
