The Thin-Lens Equation
This essay will tell about The Thin-Lens Equation but before we begin with the equation. We will have to learn what is the meaning of Thin lens.
The word lens comes from the Latin word for lentil, a seed whose shape is similar to that of a common lens. An optical lens is made from some transparent material (most commonly glass but sometimes plastics or crystals). One or both surfaces usually have a spherical contour. Biconvex spherical lenses (both surfaces convex) and biconcave spherical lenses (both surfaces concave).
The Helium-Neon Laser
The He-Ne laser is one of the most commonly used visible light lasers, giving off a red laser beam with a wavelength of 0.632mm. It has been used extensively for medical treatment, holography, laser light displays and more. Its low cost and long lifetime make it extremely convenient for use. However, the sole weakness of this laser is low output power limiting the number of applications, especially medical applications, which can be done with this laser.

Light and Color
Light is electromagnetic (EM) radiation, the fluctuations of electric and magnetic fields in nature. More simply, light is energy and the phenomenon of color is a product of the interaction of energy and matter. As a reasonable starting place for discussing color, we need to take a brief look at the physics of light and the particular nature of light sources.
The Concept of Light
Of all the senses, vision supplies us with more information, both in quantity and in detail, than all the others combined. What we see depends fundamentally on the properties of light as well as the physical and psychological processes of interpretation. It is no wonder that the nature of light has always been a subject of great speculation and interest. In spite of this wide interest and many attempts at explanation, just what light is remained in dispute until the first decade of the twentieth century.
Double Slit Interference
Displacement y = (Order m x Wavelength x Distance D)/(slit separation d)
Diffraction by a single slit
The breaking up of a ray of light into dark and light bands or into the colors of the spectrum caused by the interference of one part of the beam with another when the ray is deflected at the edge of an object or passes through a narrow slit is called a single slit diffraction.
