Why angle of incidence is taken with the normal in reflection of light?

In the case of reflection, it makes little difference whether it is the angle with regard to the normal or the tangent to the surface since these are simply complementary angles. However, when studying refractions, there is a simpler relationship in the direction of the light ray in terms of the angle relative to the normal.
Furthermore many mirrors do not reflect at their surface: the light ray travels through some thickness of glass before hitting the reflecting surface, and the travels through a the medium again before returning to the basic medium: air. There may be times - particularly with thicker glass - when refraction needs to be factored into the calculation of the path of the light beam.

What are angle of reflection and angle of incidence?
The angle of incidence is the angle between the incident ray of radiation (usually light) and the normal (perpendicular) at the point of incidence. Similarly, the angle of reflection is the angle between the reflected ray and the normal.
How is the angle of incidence of light ray related to the angle of reflection?
For a smooth surface, the angle of incidence is the same as the angle of reflection.
Why is it easier to measure the angle of incidence an the angle of reflection n a flat surface?
When talking about reflection (normally with light), one works out the angle of incidence and the angle of reflection by drawing a line that is perpendicular (90 degrees) to the reflector and measuring the angle between this line and the ray of incidence/reflection. This line is called the normal line. It is easier to measure the angles of incidence and reflection on a flat surface, because it is easier to draw an accurate normal line.
When light is reflected from smooth surface the angle of incidence is?
The angle between the light ray and the normal (perpendicular) to the surface at the point of reflection.
When light is reflected is the angle of incidence at right angles to the angle of reflection?
Not usually. (Only when the angle is 45 degrees.)"The angle of incidence is equal to the angle of reflection."
What are angle of reflection and angle of incidence?
The angle of incidence is the angle between the incident ray of radiation (usually light) and the normal (perpendicular) at the point of incidence. Similarly, the angle of reflection is the angle between the reflected ray and the normal.
What are value of angle of incidence and angle of reflection for normal incidence of light on mirror?
The angle of incidence is 0 degrees for normal incidence, meaning the light ray hits the mirror perpendicularly. The angle of reflection is also 0 degrees, as the reflected ray will be in the same direction as the incident ray.
What happens when normal incidence strikes mirror?
When light with normal incidence strikes a mirror, it reflects back at the same angle in the opposite direction. This is known as specular reflection, where the angle of incidence is equal to the angle of reflection.
The angle that the reflected light ray makes with the normal is called the angle of?
The angle of incidence
What are the angel of reflection and the angle of incidence?
The angel of reflection refers to the angle at which light is reflected off a surface, equal to the angle of incidence where the light strikes the surface. The angle of incidence is measured between the incident light ray and the normal (perpendicular line) to the surface at the point of incidence.
According to the Law of Reflection the angle of incidence the angle of reflection.?
According to the Law of Reflection, the angle of incidence (the angle between the incoming ray and the normal to the surface) is equal to the angle of reflection (the angle between the reflected ray and the normal). This law applies to the reflection of light off a smooth surface.
What are the angle of reflection and the angle of incidence?
The angle of incidence is the angle between the incident ray and the normal to the surface at the point of incidence. The angle of reflection is the angle between the reflected ray and the normal to the surface at the point of reflection. According to the law of reflection, these two angles are equal.
The angle of incidence is always greater than the angle of reflection?
No, the angle of reflection is always equal to the angle of incidence according to the law of reflection. When light or other waves reflect off a surface, the angle they make with the normal (perpendicular line) to the surface upon reflection is the same as the angle they made with the normal upon incidence.
In reflection what is the normal?
In reflection, the normal is a line that is perpendicular to a surface at the point where the light ray strikes. It is used to determine the angle of incidence and the angle of reflection of a light ray.
How are incident ray reflected ray and normal related?
The incident ray, reflected ray, and normal are related by the law of reflection, which states that the angle of incidence is equal to the angle of reflection. The incident ray is the incoming ray of light, the reflected ray is the ray of light that bounces off the surface, and the normal is an imaginary line perpendicular to the surface at the point of incidence.
When light shines on a mirror how are the angle of indence and the angle of reflection releated?
The angle of incidence, which is the angle between the incoming light ray and the normal (perpendicular) to the mirror, is always equal to the angle of reflection, which is the angle between the reflected light ray and the normal. This relationship is described by the law of reflection.
Why does the angle of reflection increase as the angle of incidence increases?
As the angle of incidence increases, the angle of reflection also increases due to the law of reflection, which states that the angle of incidence is equal to the angle of reflection. This is because light behaves in a predictable manner when reflecting off a surface, and the angles are always equal in relation to the surface normal.
