I saw my high school physis teacher put an LED into the earphone jack of a simp le radio shack radio, and about 4 feet away, put a phototransistor (?) into the microphone jack of a small amplifier, the sound was carried by the pulsing LED . I would like to re-create this experiment using a laser from the rooftop of one campus building to another. How would I go about this, is it possible, and what materials would I need? Thanx!
