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 else can I help you with?
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.
Whose ideas led to the atomic theory of matter?
The atomic theory of matter can be attributed to the ideas proposed by the ancient Greek philosopher Democritus. He hypothesized that all matter is composed of indivisible and indestructible particles called atoms, which differ in shape, size, and arrangement. Democritus' atomic theory laid the foundation for modern atomic theory.
Using the particle theory of matter why does gold become a soluble in water when combined with cyanide?
Gold becomes soluble in water when combined with cyanide due to the formation of a cyanide complex with the gold ions. The cyanide ions surround and bind to the gold ions, allowing them to be carried away in water. This process is explained by the particle theory of matter, where the interactions between the gold and cyanide particles result in the formation of a new substance with different properties.
Which process can be explained by the kinetic-molecular theory condensation ccombustion or oxidation?
Condensation can be explained by the kinetic-molecular theory. It occurs when gas molecules lose energy and come together to form a liquid. Combustion and oxidation are chemical processes that involve the reaction of substances with oxygen, rather than the behavior of gas molecules.
How did scientists discover subatomic particles?
Scientists discovered subatomic particles through experiments with particle accelerators and detectors, which allowed them to observe the behavior of particles at extremely high speeds and energies. By studying the results of these experiments, scientists were able to identify and characterize subatomic particles such as electrons, protons, and neutrons.
2 How did Dalton support his theory that all matter is made up of atoms?
Dalton supported his theory by conducting chemical experiments that showed elements combining in simple whole number ratios. He proposed that these ratios could be explained by the presence of indivisible particles called atoms. Additionally, his theory successfully explained the law of conservation of mass and the law of definite proportions.
How is the states of matter explained in the atomic theory?
Pressure(p)=6, diameter(d)=100
What observations or experiments do not show light behaving as a classical wave?
Certain experiments such as the photoelectric effect and the Compton effect cannot be explained by classical wave behavior. The quantized nature of light revealed by these experiments led to the development of the quantum theory of light.
What were the experiments Einstein do?
Albert Einstein conducted the thought experiments that led to his theory of relativity. These included imagined scenarios involving trains, elevators, and light beams to explore the nature of space, time, and gravity. His famous theory laid the foundation for modern physics.
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.
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.
Which process can be explained by the kinetic theory?
Diffusion can be explained by the kinetic-molecular 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.
How do experiments help scientist learn about the world?
experiments test the scientist theory
Does the theory of evolution explain the origin of life?
No, the theory of evolution explains the changes in species over time through natural selection. The origin of life is explained by abiogenesis, which is the theory that life arose from non-living matter.
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.
Why did newton prove Galileo's theory?
Newton explained his theory
