The Lambert Cosine Law states that the intensity of light reflected off a surface is directly proportional to the cosine of the angle between the incoming light and the surface normal. This law helps to explain how the brightness of a surface changes based on the angle of incidence of light.
Yes. Lambert's law is a cosine function describing reflected light intensity. In practical terms it means you see maximum light intensity when you look head on at something, but the intensity drops off as you move to one side or the other. A graph of the rate at which it drops off mimics the cosine graph.
Refraction and Diffraction are two words that also relate to light. Refraction is the bending of light as it passes through different mediums, and diffraction is the bending of light as it passes around obstacles.
The bouncing back of light is called Reflection
Absorption and reflection are two ways in which light and sound waves interact with surfaces. Absorption occurs when waves are taken in by a material, converting their energy into heat. Reflection, on the other hand, happens when waves bounce off a surface without being absorbed. In the context of light and sound waves, absorption and reflection are related in that they both affect how waves behave when they encounter different materials or surfaces.
The reflection of light from a rough surface is called diffuse reflection. Unlike smooth surfaces that exhibit specular reflection (reflecting light uniformly in one direction), rough surfaces scatter light in various directions, causing the reflection to be diffused.
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection. The angle of incidence is equal to the angle of reflection because the light ray selects the shortest path to reach the destination. This behavior of light is known as Fermat’s principle.

Lambert Point Light was created in 1872.
Optics deals with light waves, and all waves relate in some way to trigonometry. Also, the reflection and refraction of light involves trigonometry.
Reflection
no reflection basically deals with light rays. so there is no reflection withou light.
When the rays of light do not follow the laws of reflection, then this type of reflection is called diffused reflection.
Reflection of light from a rough surface is known as "Diffused" or "Irregular" reflection, because the light rays are barely seen after the reflection of light from a rough surface.
Refraction and Diffraction are two words that also relate to light. Refraction is the bending of light as it passes through different mediums, and diffraction is the bending of light as it passes around obstacles.
The bouncing back of light is called Reflection
A shadow is the absence of light, a reflection is just that, the reflection of light. So a shadow comes from blocking a light source, a reflection comes from the bouncing of light of one source and on to another
Reflection of light is the bending of light from its point. while refraction is the diverging of light from its bearing.
