Cut the potato in half, firmly press it against the socket and begin twisting counter-clockwise. The potato should grip the base of the bulb and turn it while the socket remains still.
Can light pass through black paper?
Now black paper absorbs most light, whereas white paper reflects some of the incident radiation (light). Hence, black heats up more than white. Answer 2: … Black paper gets warmer than white paper when exposed to sunlight because black absorbs more radiation (in the form of heat and light energy) from the sun.
