This OpenLearn course provides a sample of level 2 study in Biology...Obesity:...

...energies remained the same. Decreasing the wavelength of the light, however, caused the electrons to be emitted with a higher maximum energy. Conversely, increasing the wavelength of the light beyond a particular cut-off value (specific to each metal), caused the emission of electrons to cease. The explanation was that light interacts with matter as if it is composed of a...
