Reflection, refraction

Refraction at spherical surfaces and lenses can be easier to understand if we explore each term individually. Now, there are numerous phenomena of refraction that occur in nature; some of them include the glare of stars, pre-sunrise, post-sunset, etc. The ability of lenses to converge or diverge the rays of light passing through them is […]

Light is fascinating to observe and understand. When light passes through a medium, several phenomena take place. One of them is Refraction. Refraction refers to a change in the direction of light when it travels from one medium to another. Refraction is dependent on the refractive index.  The Refractive index can be defined as a

The eyes are the most crucial organ of the human body. All the things in our surroundings are only visible because our eyes see them. Our eyes are connected with our brains. The nerves present in our eyes first see the pictures, and then our brain understands them. The actual part of understanding the image

Also known as Huygen-Fresnel Principle, Huygen’s Principle was introduced by Dutch mathematician, physicist, and astronomer Christiaan Huygen in 1690. The theory has been of significance in understanding a variety of optical phenomena.  According to Huygen’s Principle, each point of a wavefront can be considered a secondary source of light, and these points emit spherical wavelets

A lens is a homogeneous transparent medium, such as a glass bounded by two curved surfaces or one curved and one plane surface. This curved surface may be cylindrical, paraboloidal or spherical, but most are spherical. A simple lens is made up of just one transparent element, whereas a compound lens is made up of

The world of light is fascinating and confusing. Objects in the mirror appear in different ways because of various phenomena. Reflection works differently for plane mirrors and spherical mirrors.  Two kinds of spherical mirrors are convex and concave mirrors. Mirrors with reflecting surfaces with an inner curvature are concave mirrors, while those with outward curvature

The light we see is always travelling in straight lines. To easily describe its path theoretically, the concept of a ray of light is used to demonstrate the direction and path travelled by light. Light rays reflect off from an object into our eyes, and we see the object via reflection. On the other hand,
