the light
Light plays an essential role in everyday life as it is necessary to complete the vision process of different organisms. It is also necessary in the process of photosynthesis in plants, which produces plant food in addition to oxygen. Light is an electromagnetic radiation that is visible to the naked eye. The wavelength of visible light is between 400 nm and 700 nm. The sun is the primary source of light from which we can see things in the day. The light has many properties. In this article we will show the refraction of light and the properties of light.
Light properties
Refraction characteristic of light: which means the change in the path of the wave when moving from center to center.
Interference property: which occurs when two two-point optical waves come out.
Diffraction and diffusion: which occurs when light passes through a narrow opening so that it spreads from the other side.
Polarization: This occurs when two crystals are placed on top of each other so that they are moved on one another at an angle of 90 degrees.
Reflection: It occurs when the light falls on a particular object and the body absorbs light energy and then sends it in different directions.
Photovoltaic phenomenon: which causes the emission of electrons when the light falls on a metal surface.
Chemical Phenomenon: This enables light to change the chemical properties of the surfaces that fall on them.
Information on refraction of light
He defines the refraction of light as one of the physical phenomena known to classical physics.
The phenomenon of refraction occurs due to the difference in the speed of light in each medium through which it passes.
The speed of light is as large as possible in the air, and it is reduced in glass.
The refraction of light occurs as a result of a change in the direction of the optical beam when it crosses the surface, which separates two different colors and is transparent and different in density.
A beam of light travels off the beam that moves toward the separating surface, corresponding to the point of fall.
The refracted beam of light reflects the new path taken by the beam in the second medium after it has reached the surface separating the two centers.
The angle of refraction reflects the angle between the refracted beam and the pole from the point of fall, and it is on the surface separating the two centers.
An increase in the angle of fall leads to an increase in the angle of refraction.
Note that when the light falls on the vertical surface vertically, it is carried out without breaking.
