What is principle of Rainbow ?
Rainbow is a natural phenomenon showing dispersion.
Rainbow is a natural phenomenon showing dispersion.
Splitting of light into its colours is known as dispersion of light.
Reflection from a smooth surface like that of a mirror is called regular reflection.
When all the parallel rays reflected from a rough or irregular surface are not parallel, the reflection is known as diffused or irregular reflection.
an image formed by a mirror the left of the object appears on the right and the right appears on the left. This is known as lateral inversion.
The angle between the normal and the reflected ray is known as the angle of reflection (∠r)
The angle between the normal and incident ray is called the angle of incidence (∠i).
Draw a line making an angle of 90º to the line representing the mirror at the point where the incident ray strikes the mirror. This line is knownas the normal to the reflecting surface at that point
The ray that comes back from the surface after reflection is known as the reflected ray
After striking the mirror, the ray of light is reflected in another direction.The light ray, which strikes any surface, is called the incident ray.
