The angle of incidence refers to the angle at which a ray of light hits a surface or interface between two materials. It is measured between the incident ray and the normal to the surface at the point of incidence.
The angle of incidence can be calculated using the formula: angle of incidence = inverse cosine (opposite side/hypotenuse).
According to the law of reflection, the angle of incidence is equal to the angle of reflection. This means that the incident ray and the reflected ray will make the same angle with the normal to the surface.
Yes, the size of the angle of incidence does affect the amount of light reflected. When the angle of incidence is larger, more light will be reflected. However, when the angle of incidence is smaller, more light will be refracted and less will be reflected.
The size of the angle of incidence determines the position and size of the image formed by a lens or mirror. A larger angle of incidence will result in a larger and more distorted image, while a smaller angle of incidence will result in a smaller and clearer image.
