Providing the basis of nineteenth century physics, Young's Double Slit Experiment proved that light

This helped form empiricism which says that what we know comes from experience and that observing and experimenting enable scientific knowledge

One of J.J. Thomson's most significant contributions to science, and thus to the study of atomic theory, was his discovery of the electron. Before the discovery of the electron, the atom was already associated with having electric charges-both positive and negative-but the idea of an electron existing as its own particle was unheard of. It was in 1897 when Thomson first conducted the beginning of his now famous experiment, in which he used a cathode ray tube to aid in his findings. A cathode ray tube, is a vacuum tube in which cathode rays, negatively charged particles, are produced at the cathode and travel through the vacuum, which is created when gas is extracted from the tube. J.J. Thomson discovered that in order to determine

Later on, he accomplished and developed the general theories of relativity which “helped make predictions concerning light and gravitation” (“Albert Einstein”. 5). Einstein’s first prediction was “that a red shift is produced if light passes through an intense gravitational field, and this was subsequently detected in astronomical observations in 1925. The second was a prediction that the apparent positions of stars would shift when they are seen near the sun because the sun’s intense gravity would bend the light rays from the stars as they pass the sun” (5).Later on, “one of the deep

Light waves are a form of electromagnetic waves, which consist of patterns of electric and magnetic energy. The visible spectrum is only a small part of the electromagnetic spectrum-the

“The lights that filled the universe could be channeled, dissected, magnified, and measured by human ingenuity” (enlight, 2). There was a significant breakthrough in regards to what could be done in continuing to explore new theories.

Quantum Mechanics is the science of subatomic particles and their behavior patterns that are observed in nature. As the foundation of scientific knowledge approached the start of the twentieth century, problems began to arise over the fact that classic physical ideas were not capable of explaining the observed behavior of subatomic particles. In 1913, the Danish physicist Neils Bohr, proposed a successful quantum model of the atom that began the process of a more defined understanding of its subatomic particles. It was accepted in the early part of the twentieth century that light traveled as both waves and particles. The reason light appears to act as a wave and particle is because we are noticing the

We benefit greatly the benefits of long distance communication, eating food from different parts of the countries without fear of spoilage, radiation treatment, and heating up food in a matter of minutes, and a myriad of other wonders all do the wonders of waves, be they sound waves as well as light waves. In this timeline, we will look at all of the different light waves, their history, and their benefits.

HS-PS4-1. Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media

The use of light as water is an example of the "closeness or near-merging of two realms, two worlds" (Faris 172). The two realms that I speak of are the realm of reality and the realm of the imaginary. This element becomes obvious when the two brothers "filled the apartment to depth of two fathoms, dove like tame sharks under the furniture, including the beds, and salvaged from the bottom of the light things that had been lost in darkness for years" (159).

Crick and Watson used X-ray diffraction data, which Rosalind Franklin developed which was then used to develop the ‘double

If asked what light is, one could say that it's one of the most basic

He proposed that under certain circumstances light could be considered a particles. He also hypothesized that the energy carried by a photon is depositional to the frequency of radiation. The formula E= HU proves this. Virtually no one accepted this theory but thought differently when Robert Andrews Millikan proved it.

With today’s science, light becomes more specifically perceived as a spectrum. The specific name for this spectrum is the electromagnetic spectrum, which contains many types of waves (NASA, Electromagnetic Spectrum). In Figure 2, the spectrum shows a variety of wavelengths with specific wavelengths classified by its length. The range of wavelengths humans can see wavelengths that are around 400 – 700 nanometers (nm) as colors while all other electromagnetic waves are simply blind to humans. The interesting classes for light that are used to measure are microwave and infrared light. The laser is

Before Einstein, Scientists believed that light waves travelled through a medium called ether. Einstein proved that ether was irrelevant and that light doesn’t travel through a medium. Einstein proved this by figuring out that the speed of light was constant, and in order for ether to be the medium light waves travel through, the speed of light would change depending on the observer. This discovery was one piece of the Specific Theory of Relativity.
