What happens to a ray of light which strikes normally to a smooth surface?
In reflection, a light ray strikes a smooth surface, such as a mirror, and bounces off. A reflected ray always comes off the surface of a material at an angle equal to the angle at which the incoming ray hit the surface. When light hits paper, the waves are reflected in all directions.
What happens when parallel rays of light falls on a curved reflecting surface?
Parallel beam of light falls on a curved reflecting surface: If the surface of the mirror is curved and different parts of a light beam will fall on it at different angles of incidence. So, they will be reflected in different directions. Both angle incidence and reflection angle is equal.
Which of the following happens when light is reflected from a smooth surface?
Regular reflection occurs when light reflects off a very smooth surface and forms a clear image. According to the law of reflection, the angle at which light rays reflect off a surface is equal to the angle at which the incident rays strike the surface.
When a ray of light strikes a smooth mirror surface at an angle to the perpendicular The ray is reflected?
A light ray that strikes an object consisting of two mutually perpendicular reflecting surfaces is reflected back exactly parallel to the direction from which it came ((Figure)). This is true whenever the reflecting surfaces are perpendicular, and it is independent of the angle of incidence.
What happens when a parallel beam of light falls on a curved reflecting surface Class 7?
A spherical mirror whose reflecting surface is curved outwards is called a convex mirror. A parallel beam of light falling on this mirror converges at a point after reflection. A parallel beam of light falling on this mirror appears to diverge from a point after reflection. It is also called a converging mirror.
What happens when light hits a curved surface?
The bending of a ray of light also occurs when light passes into and out of a glass lens. However, because of the curved surfaces of the lens, the bending causes the light rays in a beam either to come together (converge, picture on left-hand side) or to spread out (diverge, picture on right-hand side).
What type of reflection is illustrated when light falls on smooth surface such as mirror or a calm body of water?
Reflection off of smooth surfaces such as mirrors or a calm body of water leads to a type of reflection known as specular reflection.
When a light ray strikes a smooth flat surface What is the relationship between the angle of incidence and the angle of reflection?
For a smooth surface the angle of incidence (θ1) equals the angle of reflection (θ2), as measured with reference to the normal (line perpendicular) to the surface. Encyclopædia Britannica, Inc. Figure 7: The refraction and reflection of light.
What happens when the light hits the mirror?
When light hits a flat mirror, it is reflected to our eyes. It is also reflected to the rest of our bodies. It does not bounce perfectly off of our heads, eyes or other body parts facing the mirror. The rays that are refracted from our bodies then hit the mirror at varying angles and are reflected back perfectly.
When light falls on a smooth polished surface most of it?
When light falls on a smooth polished surface, most of it is reflected in the same direction., and this type of reflection is known as regular or specular reflection.
