| Student Manual |  Everyone of us has come across a light bulb. In this "think-aloud activity" we invite students to look at its physics. There are multiple expects one can explore such as the bulb's electrical, thermal or optical properties. Does the bulb look like a black body? What is it's filament's temperature? Does the bulb satisfy Ohm's law? Does the light emitted from a bulb follow an inverse-square law, any other power law? |
