I2-43: CONVECTION - HOT PLATE
Additional Info
- ID Code: I2-43
- Purpose: See convection currents.
- Description: The irregular refraction patterns created by convection currents in air heated from below are easily seen when light from a point source (foreground) shines through the air over a hot plate and 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.
- Availability: Available

- Loc codes: I0, LS1
