The light spectrum is the collection of colours that are generated when light is dispersed through a medium, such as a prism. This dispersion reveals the various wavelengths of visible light, with each wavelength corresponding...

Radio Astronomers discovered hundreds of Quasars hiding in our galaxy.

The 1990s saw a boom in alien abductions in popular culture, fueled by shows like The X-Files and Hollywood blockbusters such as Independence Day. UFO enthusiasts, ranging from skeptics to believers, grew in number, driven by both...

While the sun seems yellow to you from childhood, in reality, it is white. The reason why the sun appears yellow is because of the Earth’s atmosphere. When sunlight hits atmospheric particles, it causes electrons and protons to vibrate...

There are three main reasons why we don’t see all the colors in a rainbow: 1. The colors we see in a rainbow are spectral, which means they are also present in the visible spectrum. 2. Some colors, like pink and brown, are made when two...

The atmospheric composition of the sky affects the colours we see. From blue horizons to red sunsets, why do we see colours the way we do? Physics - Our Solar System - Learning Points. Light is made up of different wavelengths. Our...

What is refraction and how does it produces the colours and shape of a rainbow? Earth Science - Weather - Learning Points. Rainbows are beautiful tricks of the light. Rainbows are caused when light is reflected and refracted by water....

The world appears to be a colourful place, but what are colours? What properties of light determine what colour we see? Physics - Waves - Learning Points. Colour is how our brains perceive different wavelengths of light. Newton...
