Transmitted intensity is defined as the energy that ______.

Transmitted intensity is defined as the energy that ______.

• A. Returns toward the source
• B. Absorbed energy
• C. Continues forward in the same general direction
• D. Remains at boundary

Answer: (C)

Transmitted intensity is the portion of incident energy that makes it into the second medium and travels away from the boundary. It represents energy that passes through the interface, unlike energy that is reflected back toward the source or energy that is absorbed by the material. The transmitted beam can change direction due to refraction, but it continues moving forward into the new medium rather than remaining at the surface. So, the energy that continues forward in the forward direction best describes transmitted intensity.
