How to Stop Light in Its Tracks
Scientists have created beams of light that are slower than a car! Not only that, but with the literal flick of a switch, they can freeze that beam of light in place!

Spectra Interference: Crash Course Physics
Light is everywhere … but it’s not as predictable as you might think. It’s a wave that travels in straight lines, yet it also reflects off of surfaces, refracts through various materials, and generally changes direction all the time!...

Colour
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...

Ray diagrams
Why can you see your reflection in some objects? In this video we will look at ray diagrams for reflection, refraction and colour absorption. Visible light is part of the electromagnetic spectrum. Light is a transverse wave, and travels...

What is Color?
"To understand the phenomenon of color, it helps to think about light as a wave." This is a brief and very informative instructional video on what color is and why we are able to see it. Your young scientists will learn such terms as the...

STEMbite: Polarization of Light
Here is a backyard explanation of the polarization of light. Using his porch railing, the video narrator demonstrates that if the grating is lined up with the direction of light waves, represented by a hula hoop, the waves are allowed to...
