please answer me
not with animation write in page and draw reflection of light in paper

What is Reflection of Light?
The process through which light rays fall on the surface and gets bounced back is known as a reflection of light.
Types of Reflection:
Regular Reflection:
The plane mirrors with a smooth surface produce this type of reflection. In this case, the image is clear and is very much visible. The images produced by plane mirrors are always virtual, that is they cannot be collected on a screen.
In the case of curved mirrors with a smooth surface, we can see the images of reflection either virtually or really. That is, the images produced by curved mirrors can be either real (collected on a screen and seen), or virtual (cannot be collected on a screen, but only seen).
Irregular Reflection:
Unlike mirrors, most natural surfaces are rough on the scale of the wavelength of light, and, as a consequence, parallel incident light rays are reflected in many different directions irregularly, or diffusely. Hence, diffuse reflection helps in seeing the objects and is responsible for the ability to see most illuminated surfaces from any position.
Law of Reflection Formula:
The law of reflection formula is given as:
θi = θr
Where,
- θi is the angle of incidence
- θr is the angle of reflection
Uses of Reflection:
- Reflection is used in periscopes to view advancing enemies on the battlefield from a safe position.
- Reflection is the reason why we see objects.
- Reflection by a concave mirror and a convex mirror has many uses as listed above.
- Reflection helps in medical diagnosis and optical communications.
- Light and Sound both follow the law of reflection, both being waves.
Answer:
There are two laws of reflection:-
- The ray of incidence, ray of reflection and normal drawn at the point of incidence to the reflecting surface life in the same plane
- The angle of reflection and angle of incidence are always equal.
