WebIn contrast, the light from a star moving away from us seems to shift towards longer wavelengths. As this is towards the red end of the spectrum, astronomers call it redshift. Top: the light spectrum of an object at rest. Bottom: the light spectrum of that object moving away from you. Notice how the lines shift towards the red end of the spectrum. WebApr 9, 2024 · Mathematically, we can express this as. c = λ f. where the Greek letter for “l”—lambda, λ —is used to denote wavelength and c is the scientific symbol for the speed of light. Solving for the wavelength, this is expressed as: λ = c f. Example 5.1. 1: Deriving and Using the Wave Equation. ct dph flu

"WebEinstein 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. This concept is now known as wave-particle duality. Einstein won the 1921 Nobel Prize in ... " - Some ways light is observed
