Unformatted text preview: Continuous vs. Quantized E = h h = 6.63x10-34 Js (Plancks Constant) How much energy, in Joules, is present in red light (700 nm)? Light can behave as tiny particles of energy, known as photons Photoelectric Effect: when light at specific wavelengths are shined on a metal surface, energy is ejected. At other wavelengths no electrons will be ejected. Light can act as both a particle and a wave! It depends on the situation Conclusions: Light generally behaves as a wave Light is governed by two equations: o c = o E = h Energy is quantized - Max Planck The photoelectric effect demonstrates the particle-like properties of light Light can be both a particle and a wave...
