define reflection of light state 2 laws of reflection of light using a ray diagram
Answers
Explanation:
The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection. ... 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.
Definition:
The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact.
The reflected ray is always in the plane defined by the incident ray and the normal to the surface at the point of contact of the incident ray.
The images produced by plane mirrors and curved mirrors can be understood by the law of reflection.
Law of reflection is defined as:
The principle when the light rays falls on the smooth surface, the angle of reflection is equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.
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.
