Light is commonly described in terms of brightness and colour. Copy and complete the following table by filling in the quantities in the wave and particle models of light which relate to colour and brightness. Particle Model Brightness Colour Wave Model 2. Electrons are ejected from a surface when light of a certain frequency is incident upon the surface. What would happen to the maximum kinetic energy of the individual ejected electrons if a. the intensity of illumination was doubled? b. the length of time of exposure to light was doubled? c. the frequency of the light was doubled? d. the material of the surface was changed? Explain your answers. Light is commonly described in terms of brightness and colour.
