Note – It is not reflection, reflection happens for all angles.
That angle is called the Critical Angle. This phenomenon is called Total Internal Reflection. When light travels from an optically denser medium to an optically rarer medium at a more than specific angle, it will come back in the same medium. This makes them particularly useful for blind corners, sharp bends, and your driveway if you can’t see the oncoming traffic.Ĭheck what is Polarization of Light here. Convex mirrors allow you to see around corners and bends. Doctors use concave mirrors because images formed by concave mirrors are larger in size than the original objects. A concave mirror has converging power, it can concentrate the light ray at a particular point. Concave mirrors are used in car headlamps. Where u is the distance between object and pole (P), v is the distance between image and pole (P) Conditions of Reflection through Spherical Mirror Radius of curvature (R) = Focal Length (f) There are two types of spherical mirrors: concave, and convex. Distance between object and image is two times the distance between object and plane mirror.Ī spherical mirror is a mirror that has the shape of a piece cut out of a spherical surface. 
Reflection of light examples full#
To see a full object image in a plane mirror, the height of the mirror must be greater or equal to the height of the object.Reflection of light from different types of mirror Plane Mirror The incident ray, the reflected ray and the normal to the mirror at the point of incidence all lie in the same plane.
The angle of incidence is identical to the angle of reflection.When a ray of light falls on a boundary separating two media and then bounces back into the same media, this phenomenon is called the reflection of light. Reflection and Refraction of Light FAQs.
