What is the angle that light strikes a surface?
That is known as the angle of incidence. It is measured from the normal, which is a imaginary line perpendicular to the surface at the point where the light wave contacts the surface.
Why is reflection is important?
Whenever a ray of light strikes a surface, at least some of the light is reflected --that is, it bounces off the surface toward a new direction. The surface does not have to be flat or shiny to reflect light; light bouncing off rough surfaces, such as grass or pavement, is reflected in many different directions. This is called diffuse reflection. However, if the surface is both flat and shiny, the light bouncing off it will behave in very specific ways--the reflected rays will be parallel, and they will reflect in an easily calculated angle. This type of reflection is called specular reflection, and it has been used by scientists for centuries to better understand light itself. In specular reflection, the light ray will strike a reflecting surface at some angle (known as the angle of incidence) and bounce away at another angle (the angle of reflection). These angles are measured relative to an imaginary line, called the normal, which is drawn from the point where the ray strikes the reflecting surface and is perpendicular to that surface. As measured from the normal, the angle of reflection will always be equal to the angle of incidence. This is the most important law governing the reflection of light and was first noted by the ancient Greek engineer Hero (first centurya.d. ).
What Is an imaginary line perpendicular to the surface of a medium where a wave strikes it?
* base line * orthogonal projection * Versine co-ordinate The above may (or may not; the first two seem wrong and I don't think I've ever heard of the third) be correct, but I suspect the term you're looking for is surface normal or normal vector.
Lightning sometimes leaves behind a strange calling card what is it called and how is it formed?
If lightning strikes a sand bed, it will form a fused tube in the sand, known as Fulgurite. This form is not confined to surface conditions, tubes are found up to 15m below the surface, and Fulgurite tubes may be up to a few cm in dia.
Describe the path of the light ray that hits a mirror after passing through its focus?
It is reflected back parallel to the principal axis. (apex)
Part of a meteroid that strikes Earths surface?
Part of a meteoroid that strikes earth's surface is known as a meteorite. These are some of the bodies that are found in outer space.
What is the difference between an incident ray and a reflected ray?
The ray which hits or falls on a object or a material initially is known as INCIDENT RAY. The ray which gets reflected after hitting the object is known as REFLECTED RAY.

Definition of reflected ray for a plane mirror?
angle of reflection [′aŋ·gəl əv ri′flek·shən](physics) The angle between the direction of propagation of a wave reflected by a surface and the line perpendicular to the surface at the point of reflection. Also known as reflection angle.
