- The speed of light can change. The highest ever recorded is 299 792 458 m / s. In 1998, Danish physicist Lene Vestergaard Hau led a combined team f...
- yeah! for example some lightbulbs are more "warm" and orangy and some are more white
- Any kind of Electro-Magnetic wave travels in small energy packets called photons. In the visible range of light these are called photons and in the...
- actually, you thrown ball does make a wave. its just that the wavelength is so small, you could not observe or measure it DeBroglie said: Wavelengt...
- Photons can be absorbed by electrons. These will increase in energy and jump energy levels. Afterward, the same electron can emit the photon to jum...
- a wave can be described as the transmission of disturbance from one point to another OR the transmission of energy from on point to another
- it might be too late but ill try to answer. as per my understanding, a photon's energy is dependent only on its wavelength, that's what quantum mec...
- First you cannot treat the energy of a classical light wave the same way as the energy of a photon. The energy of a photon is E = hf. The energy of...
- c/v gives [m/s] / [Hz]. And knowing that Hz (Hertz) is equal to 1/s, then we have [m/s] / [1/s] which gives us after removing the seconds unit to g...

Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz.
Learn about light, the visible portion of the electromagnetic spectrum, and its wave-particle nature. Explore the history of light and its role in science and perception.
Learn about the wave and particle nature of light, the sources and types of light, the speed and characteristics of light, and the history of light experiments. Explore the topics of diffraction, interference, polarization, luminescence, and more.
Light - Electromagnetic, Wavelength, Spectrum: In spite of theoretical and experimental advances in the first half of the 19th century that established the wave properties of light, the nature of light was not yet revealed—the identity of the wave oscillations remained a mystery.
