The Wave Nature of Light

Interference, diffraction, thin films and polarization: the evidence that light is a transverse electromagnetic wave, the mathematics that measures its wavelength, and the technologies built on it.

Revolutions in Modern Physics

Where classical physics breaks: time and length that depend on motion, light that arrives in packets, matter that diffracts like a wave, and the small set of particles everything is made of.

Simulators

Simulators for every course →
SPH4U
Projectile Launcher

Set launch speed, angle and height and watch the path split into independent horizontal and vertical motion, with range, maximum height and flight time.

Used in 1 lesson
SPH4U
Collision Lab

Collide two carts or pucks in one or two dimensions, elastic or perfectly inelastic, and check that momentum is conserved while kinetic energy may not be.

Used in 1 lesson
SPH4U
Double-Slit Interference Lab

Change the wavelength, slit separation and screen distance and watch the bright fringes spread out or bunch together, with the fringe spacing calculated as you go.

Used in 2 lessons
SPH4U
Photoelectric Effect Lab

Shine light of any frequency and intensity on a metal and see why frequency, not brightness, decides whether electrons escape and how fast they leave.
