How to calculate the energy of a photon in Joules How fast does light travel? What is the energy of a photon of red light having a frequency of 4.3 x 1014 Hz? What is its de Broglie wavelength? How can a single photon diffract?
A joule is the SI unit of energy, representing the amount of work done when a force of one newton is applied over a meter, while an erg is a much smaller unit, used in the CGS system, equal to 10^-7 joules.
For example, pushing an object in a certain direction involves applying a force, which does work, and energy must be used up. Work and energy can both be measured in joules. Power is the rate at which energy is used up and is measured in watts. Using up 1 J of energy for one ...
One BTU is equal to approximately 1,055 joules. One joule is equal to: 1× 107 erg (exactly) 6.24150974 × 1018 eV 0.2390 cal (gram calories) 2.390 × 10-4 kcal (food calories) 9.4782 × 10-4 BTU Units defined exactly in terms of the joule include: 1 thermochemicalcalorie = ...
How many joules are in a watt? What is the rate of energy transferred called? What produces all light energy? How much energy does uranium-235 produce? What is nuclear binding energy? What is nuclear energy used for in the United States?
A registered agent for an LLC is known to be an "agent for service of processes." If an LLC does not have a registered agent, it may be fined by the state, not allowed to file a lawsuit, be denied financing, and not allowed to expand out of state. ...
David Kindness Fact checked by Amanda Jackson Investopedia / Joules Garcia What Is the Harmonic Mean? The harmonic mean is a numerical average used in finance to average multiples like the price-to-earnings ratio. It is calculated by dividing the number of observations, or entries in the series...
system'satomicparticles, whereas heat is concerned with the transfer of thermal energy, which results from the kinetic energy generated by moving particles. Temperatures can be measured in Fahrenheit, Celsius orKelvin. Heat can be measured in joules (J), calories (cal) or British thermal units ...
Eis the energy in joules; mis the mass in kilograms;andcis the speed of light, which is approximately 2.99792 x 108meters per second in a vacuum. The transformation of mass into energy also occurs during nuclear fission, in which the nucleus of a heavy element -- e.g., uranium -- spli...
What role does power play in social and political contexts? In social and political contexts, power is about the established ability to make decisions, control resources, and affect change. 9 Is might always related to physical strength? No, might is not always related to physical strength; it...
