1. I am supposed to create a device that can intensify the light directed at a light intensity sensor. A small light bulb will be 25 cm away from the light sensor. My device is required to be 20cm long and placed in between the light bulb and the light sensor in order to make the light that is entering the light sensor to be more intense. How should my device look? I believe that by trapping the light through a tunnel and at the very end I could insert a magnifying glass as it is a converging lens. However, I am worried about the focal point. Is the focal point relevant? Should my magnifying glass be at a certain distance in order to intensify light or will it intensify the light regardless. I am allowed to use any disposable, recycable and household materials in order to create this device.
