The Intensity of Light

In terms of quantum theory, increasing the intensity of light means increasing the number of photons.

Compton Scattering

In 1923, Arthur Compton’s (1892-1962) light scattering experiments provided further support for Einstein’s hypothesis for the particle nature of light.

Solid Helium

Although possible, helium does not easily solidify due to quantum effects related to its small atomic size.

Why is The Sky Blue?

Shorter wavelength blue light is scattered more by air molecules than red light. It’s this “Rayleigh scattering” that results in the blue color of the sky.

The Superheated Liquid

When a liquid has been heated to a temperature above its boiling but still doesn’t boil, it’s superheated.

The Supercooled Liquid

If a liquid is cool rapidly enough it can miss the freezing point and end up as a supercooled liquid.
