Physics Basics: The Properties of Light

Physics Basics: The Properties of Light

Light or visible light is an electromagnetic radiation that can be perceived by the human eye. Within the electromagnetic spectrum, it is situated after radio waves, microwaves, and infrared radiation, and before ultraviolet radiation, x-radiation or x-rays, and gamma rays. Nevertheless, it also exhibits all the fundamental properties of electromagnetic radiation, including the wave-particle duality. […]

Electromagnetic Waves vs. Mechanical Waves

Electromagnetic Waves vs. Mechanical Waves

Waves are disturbances and movements that transfer energy from one place to another. Both electromagnetic waves and mechanical waves are two important ways that energy can be transferred or transported around. The two also share several similarities. For starters, they can be measured and quantified by their wavelengths, frequencies, and amplitude. They can also be […]

Electromagnetic Radiation: Characteristics and Properties

Electromagnetic Radiation: Characteristics and Properties

Understanding the characteristics and properties of electromagnetic radiation can help in understanding further what exactly it is, as well as in appreciating its different forms: radio waves, microwaves, infrared, visible light, ultraviolet, x-radiation or x-rays, and gamma rays. The Characteristics and Properties of Electromagnetic Radiation Description and Definition: Classical Physics vs. Quantum Mechanics • Classical […]

What is Electromagnetic Radiation: Simplified Explainer

What is Electromagnetic Radiation: Simplified Explainer

According to classical physics, electromagnetic radiation is energy transmitted at the speed of light through oscillating electric and magnetic fields or electromagnetic waves. Also, according to quantum physics, it is described as the wave or flow of photons of the electromagnetic field that propagate or radiate through space or a physical medium, carrying electromagnetic radiant […]

Handwashing 101: How Does Soap Work?

Handwashing 101: How Does Soap Work?

The World Health Organization and other medical associations across the world have recommended handwashing using soap as one of the preventive measures against transmissible diseases. In fact, during the Ebola outbreak in Africa and COVID-19 pandemic, proper hand hygiene has been advanced as one of the solutions for containing these diseases. The Science Behind Handwashing […]

Why Is Venus Hotter Than Mercury

Why Is Venus Hotter Than Mercury?

Mercury is the nearest planet to the Sun. It orbits at an average distance of 58 million kilometers. However, despite this proximity, Venus remains the hottest planet in the Solar System. It is about twice as far from the Sun of average as Mercury. Specifically, it orbits at an average distance of 108 million kilometers. […]

Buoyancy Explained: The Archimedes’ Principle

Buoyancy Explained: The Archimedes’ Principle

Greek mathematician, physicist, and engineer Archimedes of Syracuse suggested in his 250 BCE work “On Floating Bodies,” that any object, whether totally or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. The infamous assertion made by the ancient Greek polymath is […]

Centrifugal Force: Examples and Applications

Centrifugal Force: Examples and Applications

According to Newtonian mechanics, a centrifugal force is an inertial force or an apparent force that acts on objects moving around a center or along a curved path and away from the center of the curve. Because of the force, these objects would move away from the center as they move around it or follow […]

Difference Between Absorption and Adsorption

Difference Between Absorption and Adsorption

Absorption vs. Adsorption: What is the Difference? The Basics of Absorption Absorption is a physical and chemical phenomenon in which or atoms, molecules, or ions enter or get trapped in a solid or liquid material. Unlike adsorption, the atoms, molecules, or ions are taken up by the volume and not by the surface. There are […]

Hard Disk Drive vs Solid-State Drive

Hard Disk Drive vs. Solid-State Drive

Hard disk drive or HDD and solid-state drive or SSD are two major types of data storage device. Take note that phonographic recording and optical discs, as well as DNA-based storage, are other types of storage mediums and technology. However, HDDs and SSDs are more popular because of their reasonable manufacturing cost and better storage […]
