In the case of reflection of the light from a convex mirror, when a parallel beam of light is incident on the reflecting surface, reflected light _________.
appears to converge at the principal focus
appears to diverge from the principal focus
appears to converge at the centre of curvature
appears to diverge from the centre of curvature
appears to diverge from the principal focus
When a parallel beam of light is incident on a convex mirror, the light rays diverge after reflection. If these divergent rays are extended backwards, they appear to diverge from the principal focus located behind the mirror.
When a parallel beam of light is incident on a convex mirror, the light rays diverge after reflection. If these divergent rays are extended backwards, they appear to diverge from the principal focus located behind the mirror.
Think of dropping a small pebble right in the center of a puddle of waterтАФthe ripples spread outward (diverge) away from the center point, just like light rays diverging off a convex mirror's surface.
CAVE = CONCAVE (converges); BUX = CONVEX (diverges).
f=2RтАЛ тАФ Focal length is half of the radius of curvature
f1тАЛ=v1тАЛ+u1тАЛ тАФ Mirror formula
A convex mirror is a diverging mirror. According to the laws of reflection, when parallel rays of light strike its outer bulging reflective surface, they bounce outward in different directions (diverge). Because the reflected rays spread apart, real intersection does not occur in front of the mirror; instead, they appear to come from a virtual point behind the mirror known as the principal focus.
A convex mirror is also known as a diverging mirror.
The principal focus (F) of a convex mirror is virtual and located behind the mirror.
Convex mirrors always form virtual, erect, and diminished images regardless of object position.
They are widely used as rear-view mirrors in vehicles due to their wider field of view.
Provides a wider field of view compared to plane mirrors.
Always forms erect (upright) images of objects.
Produces diminished images which makes objects appear farther away than they actually are.
Rear-view mirrors in automobiles, trucks, and motorcycles
Security mirrors in stores and blind spots on sharp turns
Option A is incorrect because convex mirrors diverge light, they do not converge it in front.
Option C and D refer to the centre of curvature, whereas parallel rays always focus at the principal focus.
B is correct тАФ reflected light appears to diverge from the principal focus.
Remember that concave mirrors converge light (real focus in front), whereas convex mirrors diverge light (virtual focus behind).
