The angle does not hit anything! A ray of light hits a mirror or glass block and the angle that the ray makes with the vertical at the point of contact is the angle of incidence.
When a ray of light hits a glass block at a 90-degree angle (normal incidence), it continues to travel through the glass block without changing its direction. This is known as refraction without deviation.

If I remember correctly, the angle that the light makes with the plane of the surface is called the incident angle.Incident angle.
It does not change.
When light hits a mirror, it is reflected back at the same angle it came in, known as the law of reflection. This causes the mirror to create a clear image of the surrounding objects if you place them in front of it.
The light ray will bend towards the normal (perpendicular line) when it moves from air into Perspex due to the change in the speed of light between the two mediums. This bending of light is known as refraction.
When a ray of light hits a mirror, it gets reflected off the mirror's surface at the same angle that it approached the mirror. This is known as the law of reflection. The angle of incidence (the angle at which the light ray hits the mirror) is equal to the angle of reflection (the angle at which the reflected ray leaves the mirror).
When light from a torch hits a mirror, most of the light gets reflected back in a predictable manner due to the smooth surface of the mirror. The angle of incidence (angle at which the light hits the mirror) equals the angle of reflection (angle at which the light bounces off the mirror). This reflection of light allows us to see our reflection in the mirror.
When a wave hits a hard surface, it reflects off the surface. The angle of reflection is equal to the angle of incidence. Some energy may also be absorbed by the surface, causing it to vibrate.
Depending on which angle the light hits, it will reflect off the mirror and go somewhere else.
When light hits the surface of an object at an angle, it can be reflected (bounced off), refracted (bent), or absorbed by the object. The amount of light that is reflected or refracted depends on the surface properties of the object, such as smoothness and transparency.
