Solid angle subtended by the finite surface at the radiating element is_________________?
Correct answer: B. Called the angle of vision
- A. Called the view factor
- B. Called the angle of vision
- C. Proportional to the square of the distance between surfaces
- D. Expressed in terms of radians
Explanation
The solid angle subtended by a finite surface at a radiating element is commonly called its angle of vision. A view factor is a fraction of radiation, while solid angle is measured in steradians rather than ordinary radians.
