I've seen some idiotic crap but this is next level. Next you'll be asking if seatbelts are necessary because occasionally someone wearing it incorrectly gets hurt. ... The photoelectric detectors work with a laser that alarms once the signal is interrupted ... The photons need a minimum threshold frequency (a minimum amount of energy) to free electrons and produce a photoelectric effect, known as the work function. In the example shown here, the violet photons have enough energy to knock out electrons, but the red photons don't. See more Photo: A typical light-dependent resistor (LDR).
