//Light is a particle:  Energy of Light is contained in small packets. bundles of energy=photons. Explains why light can travel through space. explains “Photoelectric Effect”>Energy from the light shining on a metal plate gives electrons in the metal enough energy escape. Bright light has more energy than dim light, but dim blue light can dislodge electrons while bright red light cannot. Low fre. light (red/orange) cannot eject electrons. High freq. light (blue/viol.) can eject electrons. Read More
