What two experiments involving light and matter could not be explained by the wave theory of light?

In the days before quantum mechanics there was discussion whether light was a particle or wave. The problem was that neither one could explain all phenomena completely.
For example, the particle theory couldn't not account for interference patterns that can be made with light, but the wave theory could not account for the photo-electric effect. In this effect a photon (a light particle) deposits energy into a metal causing the metal to eject an electron. The puzzling thing was that increasing the intensity of the light did not increase the kinetic energy of the ejected electrons, only the amount of such ejected electrons.
The photo-electric effect was finally tackled by Albert Einstein (for which he won the Nobel Prize in 1921), and light is now regarded as consisting of 'wave-packets' with photons have a unintuitive wave-particle duality.

What do we call the experimental apparatus that William crookes used in his experiments?
Globe theory
The merit of a new scientific theory is judged by the scientific community based on?
Experiments and repeatabilty
Whose ideas led to the atomic theory of matter?
The idea that led to the atomic theory of matter, was John Dalton.
The kinetic theory of matter states that matter is made of particles whose speed is dependent on what?
The kinetic theory of matter states that matter is made of particles whose speed is dependent on their mass and temperature. The kinetic theory states that particles in matter are always in motion.
What is the process for changing ideas?
Briefly, the scientific method essentially involves postulating a theory, and then that theory will either stand or fall on the evidence of future experiments.
How is the states of matter explained in the atomic theory?
Pressure(p)=6, diameter(d)=100
What can be inferred after performing the experiments in the atomic theory lab?
The answer to this question is dependent on what type of experiments were performed. All matter is made up of atoms, and they are very small.
Example of science theory?
A scientific theory is a structure which explains a set of empirical observations. Some well known theories: Newton's theories of motion: explained how objects moved in the universe. Einstein's general theory of relativity: explained how matter behaves in the universe. Darwin's theory of natural selection: explained why there is a huge number of related species and how new species arose.
Which process can be explained by the kinetic theory?
Diffusion can be explained by the kinetic-molecular theory.
How do experiments help scientist learn about the world?
experiments test the scientist theory
How was democritus theory accurate?
The theory of Democritus and Leukippus was confirmed 2 400 years later; all the matter is...atoms. But note that the two Greek scientists created this theory intuitively, not after experiments.
Which process can be explained by the kinetic-molecular theory?
Diffusion can be explained by the kinetic-molecular theory.
How can a scientific theory be incorrect but still be considered a good scientific theory?
If all the evidence taken into consideration can be explained by the scientific model proposed and the model successfully predicts outcomes of experiments yet to be performed, it is a "good scientific theory" It still can be incorrect. If it is proven incorrect it should be abandoned.
How do experiments help learn about the world?
experiments test the scientist theory
How is the validity of scientic theory tested?
Scientific Theory is tested by observations and experiments predicted by the theory. If the observations confirm the theory the theory is validated if not the theory is not validated. Experiments themselves need validation, often there are errors in the experiments or observations, e.g Michaelson and Morley Aether experiment and red shift observations.
What type of lessons are involved in A level chemistry?
A level chemistry lessons involve a combination of practical based experiments as well as book based learning involving the theory and learning the background of the subject.
Why did newton prove Galileo's theory?
Newton explained his theory
