Optics

If we look at a spherical mirror, the relationship between its focal length (f) and radius of curvature (R) can be expressed as f=R2, where f is half the radius of curvature and R is the focal length. Focal Length The focal length of an optical system is a measure of how strongly the system […]

A prism is a homogeneous, transparent medium bounded by two plane surfaces inclined at an angle A with each other. These surfaces are called the refracting surfaces, and the angle between them is called the angle of prism. Dispersion The dispersion of white light occurs when light passes through a prism. The splitting of white

Introduction Fringe width is obtained from Young’s double-slit experiment. This experiment was first performed by Physicist Thomas Young in 1801. So, to perform this experiment a double slit is required and monochromatic light is required. When this experiment was performed, the pattern of bright lines and dark lines showed up. From there, the concept of

In the area of ray optics, both lenses and mirrors support the advancement and development of new technological materials. However, the combination of lenses and mirrors gave a new pathway to the field and added other refinements. For enhancing the power of concentration and forming highly magnifying images through the help of refraction and reflection

We are all familiar with the Rectilinear propagation of light taught to us in early grades. The diffraction phenomenon is the bending and twisting of light around the corner of an object. When light falls incidentally on its sharp edge, a faint illumination is seen inside the geometrical shadow of the thing, indicating that light

Deviation of light by a prism Introduction A prism behaves as a light diffuser because it separates light into constituent colors with the passage of transmitted light. And deviation causes the different colors in the spectrum to spread out, creating a colorful image, then it passes into a viewing medium such as air or water.

The Beer-Lambert law, also known as the Beer–Lambert–Bouguer law or Beer’s law, asserts that a solution’s absorbance is proportional to its concentration, absorption coefficient, molarity, and optical coefficient. When monochrome light passes through a homogeneous medium, the intensity of the transmitted radiation drops at a constant rate as the thickness of the medium grows, and

As we know, our body can have different types of diseases which can be cured and improved to some extent. Like this, the human eye, which is the most complex organ of our body, also has certain types of diseases. The disease is related to the vision of the eye or the power of accommodation.

A lens is an optical transmissive device that, through the process of refraction, concentrates or disperses a beam of light. A basic lens is made out of a single piece of material that is clear in nature. A compound lens, on the other hand, is made up of a number of simple lenses, or elements,

A mirror is a reflecting surface that is highly polished and smooth. Plane mirrors are the most commonly utilised form of mirrors. The spherical reflecting surface includes a spherical mirror. Concave mirrors and convex mirrors are the two types of spherical mirrors. Mirror with a Spherical Shape Because spherical mirrors have an uniform curve and
