How will the light ray reflect if it strikes the curved mirror through its focal point?
|
|
the reflected ray will pass parallel to the principal axis
|
|
|
the reflected ray will retrace its path after reflection
|
|
|
the reflected ray will pass through the focus on the principal axis
|
|
|
the ray will be reflected obliquely
|
Explanation:
Detailed explanation-1: -Once these incident rays strike the mirror, reflect them according to the two rules of reflection for convex mirrors. The ray that travels towards the focal point will reflect and travel parallel to the principal axis.
Detailed explanation-2: -Rule 1 : If an incident ray is parallel to the principal axis then the reflected ray passes through the principal focus. Rule 2 : If an incident ray passes through the principal focus of the mirror, the reflected ray is parallel to the principal axis.
Detailed explanation-3: -A light ray directed parallel to the principal axis will reflect off the mirror through the focal point on the same side of the mirror.
