Reflection Of Electromagnetic Radiation

Satisfactory Essays
Introduction to light: Electromagnetic radiation is a form of light energy. Electromagnetic is made up of visible light, invisible light (ultraviolet, infrared, X-rays, radio waves and microwaves). In vacuum lights maximum velocity is 3.0x10^8 m/s.

Reflection: If an object does not radiate its own light, it must reflect light to be visible. Reflection includes two beams - an approaching or incident beam and an active or reflected beam. The imaginary line that is perpendicular to the principal axis is called the normal. A beam of light that hits this surface is known as the incident beam/ray. This beam/ray of light hits the surface and ricochets off (reflected beam). The point between the incident beam/ray and the normal will be indistinguishable in estimation as the edge between the reflected beam and the normal. All reflected light complies with this relationship, called Snell's Law, that the incident angle breaks even with the angle of reflection. This is the Law of Reflection.

Light going through air and then through water is a case of a light beam changing medium. The speed of the light beam changes when it enters an alternate medium. As a rule, the heading of light likewise changes. We say the light twists. when light travels in a vacuum it is at its peak speed 3.0x10^8 m/s. Contingent upon the new medium the light will travel quicker or slower. It is the distinctive densities that make the decrease in velocity which at that point makes it twist. Light beams slow down around 25% when going through water and 35% when going through glass. On the off chance the light voyages slower then this medium is known as the denser medium. In the event that the light beam ventures faster then the medium is known as the rarer medium. At the point when light enters a more optically dense medium the beam twists towards the normal. c=3.0x10^8 m/s V = fλ λ = wavelength These diagrams use Snell's
