There are 2 major statements regarding the laws of reflection:-
1. The angle of incidence = angle of reflection OR theta 1 = theta 2
and
2. The incident ray, the reflected ray and the normal (line perpendicular to the plane of the mirror/ reflective surface) all lie in the same plane.
Hope this helps.

The function and use of a dynamic cart is to provide sample tools in physics. Dynamic carts are used to demonstrate the laws of dynamics.
Reflection
A model is an explanation of why an event occurs, and how data and events are related. So theories and hypothesis are testable statements and broad generalizations to compare data and to collect data.
A scientific hypothesis is not accepted if there is no way to demonstrate the hypothesis wrong. In fact, if there is no way to demonstrate the hypothesis wrong, then it is unfalsifiable and unscientific. For example, if I hypothesize that an all-powerful being created the Universe, there is no way to demonstrate that this hypothesis is wrong. One might argue that none of the natural laws of science require the intervention of an all-powerful being, but then I would simply argue that is because the being designed things that way. Because I can come up with any unfalsifiable explanation for any objection not only is there no way to demonstrate that my hypothesis is wrong, there is also no scientific reason or evidence to believe it is right.
Diffuse reflection
you can demonstrate total internal reflection using a light source and glass gratings.
When the rays of light do not follow the laws of reflection, then this type of reflection is called diffused reflection.
Echoes demonstrate the reflection behavior of sound waves, where sound waves bounce off a surface and return back to the listener's ears.
The laws of reflection are based on the reflection of light from a smooth, flat surface. In the case of irregular reflection, where the surface is rough or uneven, the laws of reflection may not hold true as the angle of incidence may not be equal to the angle of reflection. Irregular reflection results in scattering of light in multiple directions.
No, diffused reflection does not mean a failure of the laws of reflection. Diffused reflection occurs when light rays are scattered in different directions upon hitting a rough surface, but the angles of incidence and reflection still obey the law of reflection.
The laws of reflection state that the angle of incidence is equal to the angle of reflection, the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.
angle of incidence is equal to angle of reflection.
No, it means that certain conditions are not fulfilled, so the law simply doesn't apply. Alternately, you can consider diffuse reflection as lots of small pieces of surface, each of which reflects the incoming light ray in a different reflection.
Descartes explains the logic behind the laws of reflection he discovered in his work "Dioptrics". He uses the idea of a tennis ball bouncing at an angle of the ground and up through a sheet to formulate the laws of reflection on a geometric plane.
Reflection of light is the bouncing back of light rays off a surface. The laws of reflection are: 1) The angle of incidence is equal to the angle of reflection, and 2) The incident ray, the reflected ray, and the normal to the surface all lie in the same plane.
there are two laws of reflection 1 angle of incidence is always equal to the angle of reflection 2 incident ray,reflected ray and the normal at the point of incidence lie in the same plane.
The angle of incidence is ALWAYS equal to the angle of reflection! This is one of the laws of reflection.
