Understand the phenomenon of the yellow color sun and the blue sky. Know about the common misconceptions in physics like how gravity affects light, the shape of the earth, and measuring velocity in special relativity. Discover why the sky is dark at night and why space appears dark.
Mar 12, 2024 · Although Einstein was interpreting different observations, this is the conclusion he reached in his 1905 paper: that the pure wave theory of light is an oversimplification, and that the energy of a beam of light comes in finite chunks rather than being spread smoothly throughout a region of space.
Jan 19, 2023 · One of the first experiments which is exhibited strong experimental evidence of light behaving like a particle was the photoelectric effect, which first led Albert Einstein to develop the particle model of light. In the photoelectric effect, a beam of incoming light shines on a metallic surface.
Dec 10, 2023 · Describe the photoelectric effect with Einstein's quantized photon model of light; Nature, it seemed, was quantized (non-continuous, or discrete). If this was so, how could Maxwell’s equations correctly predict the result of the blackbody radiator?
Einstein was the first to explain what was happening. He theorized that electromagnetic energy comes in packets, or quanta which we now call photons. So light behaves as a wave and as a particle, depending on the circumstances and the effect being observed.
Einstein believed light is a particle (photon) and the flow of photons is a wave. The main point of Einstein's light quantum theory is that light's energy is related to its oscillation frequency.
The theory, which revolutionized our understanding of time and space, is based on Einstein's astonishing recognition that light always travels at a constant speed, regardless of how fast you're moving when you measure it.
