The accurate statements about Hertz's observations and Einstein's photon theory are:
1. **Einstein's photon theory was necessary because Hertz's observations could not be explained by the wave theory of light.**
2. **Hertz observed that whether a metal emitted sparks when a light shines on it depends on the frequency of the light.**
The first statement about Hertz and the amplitude of light is incorrect because Hertz's experiments showed that the photoelectric effect (the emission of sparks) depends on the frequency, not the amplitude, of the light. The third statement is also incorrect as it misrepresents the context; Hertz's observations were not about the particle theory but rather about the inadequacies of the classical wave theory to explain his results concerning light's interaction with metals.
