![]() ![]() The ray of light which reflects from the mirror is known as the reflected ray. The ray of light that strikes the mirror is known as the incident ray.These reflected rays produce the image that is seen in the mirror. When you look at the image of an object in a plane mirror, the rays of light originating from the object hit the mirror and bounce or reflect from the mirror towards your eye.In diagram, the plane of the book page, is the plane of reflection. Plane of reflection: The plane in which the normal and the reflected ray lie, is called the plane of reflection.In diagram, the plane of the bookpage, is the plane of incidence. Plane of incidence: The plane in which the normal and the incident ray lie, is called the plane of incidence.In diagram, ∠QON is the angle of reflection. Angle of reflection: The angle that the reflected ray makes with the normal, is called the angle of reflection.In diagram, angle PON is the angle of incidence. Angle of incidence: The angle that the incident ray makes with the normal, is called the angle of incidence.Reflected ray: The ray of light reflected from the reflecting surface from the point of incidence, is called the reflected ray.Incident ray: The ray of light which strikes the reflecting surface at the point of incidence is called the incident ray.Normal : A perpendicular drawn on the reflecting surface at the point of incidence, is called the normal.Point of incidence: The point on the reflecting surface at which a ray of light strikes, is called the point of incidence.In diagram, XY is the reflecting surface. Reflecting surface: The surface from which the light is reflected, is called the reflecting surface.How is the Image Formed by a Spherical Mirror?.How is Focal Length related to Radius of Curvature?.Reflection of Light from Spherical Mirror.Is an Image formed by Reflection Real or Virtual.Which Type of Image is Formed by a Plane Mirror?.Applications of Total Internal Reflection.What do you mean by Total Internal Reflection?.Application of Reflection of Light in Daily Life.What is the Law of Reflection of Light?.When you look at a mirror, you see the reflection of other things around you along with your own image. This phenomenon of returning of ray of light in the same medium, is called reflection of light. (b) The picture can be seen because it reflects light from the light source.ĭefinition: When light rays are incident on an opaque polished surface (medium), these are returned back in the same medium. (a) The pictures from the television can be seen because the television emits light. These light rays can come directly from the object or as a result of the object reflecting light rays from a light source. A ray is a very narrow beam of light.Īn object can only be seen when light rays from the object enter our eyes. (b) 3 0 ∘ total internal reflection at the adjacent surface as shown.Light rays travel in a straight line. A ray of light entering from air into a denser medium of permeability 3 4 for this wavele Up to what height, the tumbler is actually filled? Bmaterials ![]() Whe [Use the fact that surface area of a 1 the ratio of he feels that the tumbler is half filled, he stops pouring h and radius of curvature r is 2 π r in meter is: water. T materials A while looking at the surface of water from the above. The thickness of the glass slab is 12 cm. (b) 2 ( 2 + 1 ) h (c) 3 2 h glass emerges out from other parallel faces and later light shin between incident ray and emergent ray is 4 3 cm. A ray of light is incident at an angle of incidence 6 0 ∘ an the ![]()
