Reflection, refraction

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

Nature has endued the human eye (retina) with the sensitivity to sight magnetism waves during various electromagnetic spectrums. The radiation happiness to the current region of this spectrum (wavelength of concerning four hundred nm at 750 nm) is named light. It’s primarily through light and, therefore, the sense of sight that we all know and

If you have ever been trekking, you must have carried polarised sunglasses with you as well. Thus, when the weather is sunny, you can’t help but notice the crystal clear reflection that appears on a lake. These reflections are polarised. However, when you see it via your sunglasses, you will see these reflections are gone.

The blue sky is one of the most commonly seen sights on Earth. It is generally defined as the sky in the daytime that appears blue because of Rayleigh scattering.   The blue colour of the sky is also referred to as cyan, azure, cerulean, and navy. The blue colour of the sky varies from

Vision problems are common. In fact, they are so common that around 2.2 billion people globally have at least one kind of eye defect. Whether it’s myopia or hypermetropia, people of different ages have these eye defects. In most cases, eye defects like myopia or hypermetropia are cured by vision correctness in the form of

Image formation is a broad concept covering different kinds of lenses, mirrors, and surfaces. Understanding how an image is formed through instruments like lenses and magnifying glasses is vital to get introduced to reflection and refraction. Moreover, it also acquaints us with the image formation on different types of mirrors. In this article, we will

A person sees lovely things all around them each day. People do not just see things; they notice, analyse and afterwards, humans either continue to stare or choose to overlook them. What gives us the ability to observe the world around us? What is the human eye that makes it so magnificent and necessary? However,
