A light ray parallel to X-axis is incident on a parabolic concave mirror in XY plane. The focus of this parabola is at (1,0). The unit vector along the reflected ray will be
Options:
Answer:
B
Solution:
A ray parallel to the axis of a parabolic mirror passes through the focus after reflection.
From the point of incidence (figure), join it to the focus (1,0) and normalize the direction vector.
The resulting unit vector matches option B.
