What Is Light?
10 min
▼
Light is one of the most mysterious things in the universe. It travels faster than anything else — about 300,000 kilometres every second. But what exactly is light? Is it a wave? Is it a particle? The answer, as you'll discover, is both! This module covers the basics of light, how it travels, and why it is so special.
▶ VIDEO
What is Light? — Veritasium
One of the best science communicators on YouTube dives into what light really is — electromagnetic radiation, photons, and the speed of light — in an engaging, mind-bending way.

Photon Electromagnetic Wave Speed of Light (c) Visible Light Wavelength Frequency
🤯 Mind-blowing fact: The light hitting your eyes right now left the Sun about 8 minutes and 20 seconds ago. Light from the nearest star beyond the Sun took over 4 years to reach us!
MODULE 02 🌈
Properties of Light
12 min
▼
Light can do amazing things: it can reflect off mirrors, refract (bend) when it moves through water or glass, diffract around corners, and even split into a rainbow of colours. These properties are what make rainbows, lenses, fibre optics, and cameras possible.
▶ VIDEO
TED-Ed: How do we see colour?
Explores how light interacts with our eyes to create the experience of colour — and why the sky is blue but sunsets are red.

PhET: Wave on a String / Wave Interference
Explore how waves work — adjust frequency and amplitude, and watch diffraction and interference patterns form. This is what light waves do too!

Reflection Refraction Diffraction Dispersion Spectrum Rayleigh Scattering
🌈 Rainbow fact: You can never reach a rainbow — it moves with you! Each person sees their own personal rainbow because the light bouncing into your eyes comes from different raindrops than the ones someone else nearby is looking at.

History: How We Understood Light
13 min
▼
For thousands of years, humans debated: what is light? Ancient Greeks thought our eyes shot beams out to "see" objects. It took centuries of brilliant experiments — by Newton, Young, Maxwell, and Einstein — to figure out the truth. The story of light is one of the greatest detective stories in science.
~300 BC
Ancient Greeks — Euclid and Aristotle debate whether eyes emit rays or receive them. Euclid writes the first known text on optics.
1021
Ibn al-Haytham (Alhazen) — The first to prove that eyes receive light, not emit it. He invents the first pinhole camera and writes a landmark Book of Optics.
1666
Isaac Newton — Uses a prism to split white sunlight into a rainbow of colours, proving white light is made of all colours.
1801
Thomas Young — Double-slit experiment shows light behaves as a wave, creating interference patterns.
1865
James Clerk Maxwell — Proves light is an electromagnetic wave travelling at a fixed speed, unifying electricity, magnetism, and light.
1905
Albert Einstein — Explains the photoelectric effect by proposing light also acts as a particle (photon) — earning him the Nobel Prize.
Today
We know light is a wave AND a particle — called wave-particle duality. This is one of the strangest and most fascinating facts in all of physics!
▶ VIDEO
The Double Slit Experiment — Kurzgesagt
Probably the most mind-bending video in science. The double-slit experiment shows that light (and even matter) does something that seems totally impossible.

🏆 Nobel Prize fact: Einstein won his 1921 Nobel Prize NOT for his famous E=mc² or relativity — but for explaining the photoelectric effect (how light knocks electrons off metal). It was this work that proved light comes in packets called photons.

Light in Action: How We Use It
12 min
▼
Light isn't just for seeing — humans have turned it into an incredible tool. From lasers that cut through steel and read Blu-rays, to fibre optic cables that carry the internet around the world, to telescopes that reveal galaxies billions of light-years away. Even solar panels work by turning photons directly into electricity!

How Lasers Work — SciShow
An engaging explainer on what a laser actually is — stimulated emission, coherent light, and why lasers are used in medicine, engineering, and your TV remote.

Weird & Wonderful Light Facts
13 min
▼
The universe has some seriously strange tricks involving light. Black holes trap it forever. Some animals can see colours we can't. Light can be slowed down to a stop — or even twisted. And one of the most shocking discoveries ever: nothing can travel faster than light, which means the past, present, and future aren't the same for everyone. Welcome to the weird frontier of light science!
