Radiant Energy

QUESTION 1

1. Using the data that you collected, graph how the energy emitted by the light bulb (in W/m²) changes with temperature (°C). Display temperature on the x-axis (horizontal) and the energy emitted by the light bulb on the y-axis (vertical). Once you have drawn a graph, digitally capture the graph on the screen and submit it through this link.
