PHOTOELECTRIC EFFECT Introduction
... Is light a continuous wave, or is it quantized in energy and space, or can it be one and the other? By observing what occurs when various wavelengths and intensities of light shine on metal, you will be able to better understand the nature of light. You also need to obtain an experimental value for ...
