81 - Light Intensity
In this experiment, you will use a light intensity sensor to determine the distance and angular dependence of the emitted light of several light sources of your choice.
- Light intensity sensor (you can use the “Light” sensor in Phyphox on your smartphone. Note: does not work on iPhones)
- Different light sources (lamp, light bulb, flashlight, projector, candle, bicycle lights, ...)
- Distance measuring device (ideally a ruler >30cm, but you can also use an arbitrary object as "lenght unit")
