6 Questions
What is the point where light rays converge for a concave mirror referred to as?
Focal point
Which of the following best describes the focal length of a mirror?
Distance between the focus and the pole of the mirror
What is the plane that passes through the focus and is perpendicular to the principal axis known as?
Focal plane
Which type of rays fall close to the pole and make small angles with the principal axis?
Paraxial rays
What happens to marginal rays in terms of their distance from the pole and angles with the principal axis?
They fall far away from the pole with small angles
Why is the study restricted to paraxial rays in this chapter?
To simplify calculations due to their small angle approximations
Learn about the concept of focus and focal length in spherical mirrors. Understand how light rays behave when incident on concave and convex mirrors, and how the focal point is related to the focal length. Explore the idea of the focal plane in mirror optics.
