Gravitational waves are ripples in the fabric of space and time, caused by violent events in the universe such as the collision of massive objects like black holes and neutron stars. These waves were predicted by Albert Einstein’s General Theory of Relativity in 1916, but were only directly detected for the first time in 2015 …

Photon splitting is a process that involves the splitting of a single photon into two photons, each having half the energy of the original photon. This process is possible when a photon interacts with a medium that has high refractive index. The split photon can have different energies from the original photon, depending on its …

Winter months can be quite challenging, particularly if you are trying to keep your heating costs down. Fortunately, there is a simple solution that not only helps reduce heating costs but also offers a range of health benefits. This solution is none other than using a humidifier. What is a Humidifier? A humidifier is a …

Electromagnetic radiation is all around us, and it is the principal source of energy on earth. It’s responsible for heating our planet, and it powers many of the technologies we rely on today. But how do molecules absorb this radiation, and how do they convert it into kinetic energy? The Electromagnetic Spectrum Before we can …

Air Pressure in a Car Tyre Increases During Driving: Understanding the Reasoning Behind It Have you ever wondered why the pressure in your car tires increases while driving? One moment you had just the right amount of air pressure in your tires and the next moment, during your journey on the road, the pressure gauge …

Hygrometers are instruments used to measure the relative humidity of the air. In simple terms, they determine how much moisture is in the air. Two main types of hygrometers are commonly used: mechanical hygrometers and electronic hygrometers. Mechanical Hygrometers Mechanical hygrometers use a combination of materials that absorb moisture and react to the changes in …

Understanding Refractive Index Base Wavelength When we talk about the refractive index of a medium, it is usually expressed as a single “number”. However, what many people may not know is that this “number” actually depends on the wavelength of the light passing through the medium. This raises an interesting question: when we state the …

A relative of mine recently came to me asking me to explain a strange physics phenomenon. She had 3 glass tables; 2 small and one large arranged neatly such that the small tables were half enclosed under the larger one. She recounted to me that one morning she was sitting in a room adjacent to …

The concept of projectile in electrostatics is a topic of interest in the world of physics. In this article, we will explore the concept of a charged particle being launched into an electric field, and how it behaves as a projectile. We will also give possible solutions to some common questions related to this topic. …
