I2-43. Convection - Hot Plate
Purpose
To see convection currents
Equipment
Hot plate and point source of light.

Description
The irregular refraction patterns created by convection currents in air heated from below are easily seen when a light from a projector shines through the air onto a screen. This phenomenon is often seen when the sun shines brightly onto surfaces like cars and roads, and is responsible for the twinkling of stars.
