The Cosmic Velocity Limit Referring to Einstein’s unique relativity theory, the velocity of light is constant in a vacuum, and that can’t be exceeded by any object. In other words, nothing can travel at a speed higher than that of light. It’s the cosmic velocity limit for data exchange. The speed of light has been …

Referring to Einstein's unique relativity theory, the velocity of light is constant in a vacuum, and that can't be exceeded by any object.

Eye accommodation is the act of physiologically making adjustment to the crystalline lens elements to vary the power of refraction and bring into sharp focus close and far objects. The eye accommodates by changing the lens’ curvature which is performed by the ciliary muscles. They relax the suspensory ligament fibers, narrow the ciliary body diameter, …

The word ‘Spectrum’ typically refers to the electromagnetic spectrum which consists of all the electromagnetic radiation frequencies. Previously, the term was limited to light only, but afterwards, it was revised to incorporate other waves, like the sound waves. The range of wavelengths is from a pico-meter to thousands of mega-meters. It contains the visible spectrum …

As we have learnt during our Physics tuition classes on Quantum Physics, electrons may take in incident energy for them to attain a higher energy state.

Lenticular lens is a strategy that has evolved immeasurably with time, and it’s even being used today. Generally, it’s a collection of magnifying lenses, which are arranged in a way that one can see diverse images magnified when observed from distinct angles. You may possibly have seen some images/pictures that produce a 3D effect when …

Lenticular technology entails exhibiting many sets of images, which vary when viewed from various angles. Depth illusion or motion illusion is then achieved .

In war, it is always important to stay a step ahead of enemy. Scientific advancement is one of the means that helps in achieving it. Science and war are in a way interdependent for the same reason. As history tells us, progress in science has played a crucial role in winning wars; on the other hand the development …

Let's discuss a very simple aspect of night vision which is one such thing that helps in staying a step ahead of the enemy in all three kinds of warfare.

RADAR stands for Radio Detection And Ranging. After the war has turned aerial, it has become essential to scour the air spaces off the enemy planes or other flying objects. Due to the humongous nature of the space that needs to searched any brute force search operation like using planes or other ground or sea means, manually, is …

RADAR was developed during world war-II separately by various nations and played a pivotal role in the war. Let's discuss the science behind RADAR

There are many light related phenomena in the sky, beyond those that we have learnt during our Physics tuition classes, such as Light Pillars, Parhelic circles, Zodiacal light and Auroras, just to mention a few. Let’s look at these events in more detail! Light pillars are an optical wonder where segments of light are seen …

Many Light related phenomena like Light Pillars, Parhelic circles, Zodiacal light and Auroras are super cool. Let's look at these events in more detail!

Halo of the Sun

Astronomy Picture of the Day (or APOD) has just released new 2015 calendars filed with magnificent photos of the Earth and space.

Refraction and Reflection

Rainbow is a curve of hues formed in the sky in specific circumstances, created by the refraction and scattering of the daylight by rain or water droplets.

Light has been one of the most interesting and challenging phenomenon to understand for a long time. Earlier theories on light were two fold, on one side were the Newtonian theory of light which said that light was composed of particles or corpuscles and travelled in straight lines and explained the entire phenomenon around the …

The wave theory and the particle theory of light failed to independently explain this phenomenon but together they seemed to have something to say.
