too. Three glowing red charcoal briquettes put out more energy than one glowing red charcoal briquette at the same temperature. Likewise, if two stars are the same temperature but different sizes, then the
What is photosynthesis and what is the basic way that plants turn solar energy into food? Plants make ATP during the light reactions of photosynthesis. Why do plants also need to carry out the process of cellular respiration? Explain what ...
In this zone, the energy from the core is carried outward by photons, or light units. As one photon is made, it travels about 1 micron (1 millionth of a meter) before being absorbed by a gas molecule. Upon absorption, the gas molecule is heated and re-emits another photon of the ...
This was Einstein's explanation: If the energy in light comes in bundles, then one can think of light as containing tiny lumps, or photons. When these photons strike a metal surface, they act like billiard balls, transferring their energy to electrons, which become dislodged from their "...
How is energy from the Sun distributed around Earth? How does a cyclotron produce protons? What is dark matter made up of? What is the cause of synchrotron radiation? How do photons carry electromagnetic force? How are oncogenes formed?
We call these individual particles of light photons: each one is a tiny packet of electromagnetic energy.Seeing with photons is fine if you want to look at things that are much bigger than atoms. But if you want to see things that are smaller, photons turn out to be pretty clumsy and ...
How do photons carry electromagnetic force? How are energy and frequency of electromagnetic radiation related? Why does refractive index vary with wavelength? Which color of the visible spectrum of the electromagnetic waves will travel the fastest in glass? Explain...
When a device like your computer has information to send, that data starts out as electrical energy. A laser in the computer converts the signals to photons – tiny particles of electromagnetic energy, otherwise known as light – and sends them in rapid succession down the core of the...
Interference is what happens when two waves carrying energy meet up and overlap. The energy they carry gets mixed up together so, instead of two waves, you get a third wave whose shape and size depends on the patterns of the original two waves. When waves combine like this, the process ...
Energy transfer competes dynamically with fluorescence emission. Therefore, Donor lifetimes Every time an excited molecule exits the excited state region by the fluorescence pathway it emits a photon. We can either count the number of photons in a longer time interval (by a steady-state measurement...
