Question

what is reflection? write at least 5 sentence?

Answer 1

Hope u like my process
=====================
=> Reflection is the flow of particle in such a opposite direction that it makes the angle with normal similar to the angle made by incident with normal

=> Reflection of a particle can be of many types..
Such as,

Reflection of light

Reflection of sound.

Reflection of waves.

=> Reflection of light can produce image if they are reflected by mirror or lens and on the screen.

=> any reflection occurs when the incident particle hits any surface.

=> with reflection their too occurs refraction and thus the intensity too decreases as incident is divided in refraction and reflection.

Answer 2

Answer: Reflection is referred to as light reflection when a light ray hits a polished, smooth surface and bounces back. The incident light rays hit the surface and are reflected off of the surface. The beam that returns back is referred to as the reflected ray.

Explanation:

1. Angles of incidence and reflection are shown here with regard to the reflective surface and the normal, respectively. On reflecting surfaces like mirrors, slick metal surfaces, and crystal-clear water, incident light rays are reflected according to the rules of reflection. According to the law of reflection, all three rays—the incident, reflected, and normal—lie on the same plane.
   Angle of reflection ∠i = Angle of incidence ∠r
2. A crisp and sharp reflection, similar to those you see in mirrors, is referred to as a specular reflection. A uniform layer of a substance that is highly reflecting, such as powder, is applied on glass to create a mirror. As a result, the haze and blurring are almost completely gone.
3. In general, reflective surfaces other than mirrors have a highly rough surface. This might be the result of surface filth or signs of wear and tear, including scratches and dents. All of this causes the reflection to lose both brightness and quality.
4. When compared between sites on such uneven surfaces, the angle of reflection is essentially random. When rays strike rough surfaces, they are reflected in radically different directions despite incident at slightly different spots on the surface. We can perceive non-shiny objects because of a reflection type known as diffused reflection.
5. One image is created when an object is placed in front of a mirror. What happens if we use two mirrors? Due to the outstanding ability of reflecting surfaces like mirrors to sustain the intensity of light in a reflection, a single light source can reflect light multiple times. As a result, there are essentially an infinite number of possible multiple reflections. We can perceive an image in every mirror. This suggests that each image is either an image of another image or a result of another image.
