What does the h in Planck constant stand for?Planck's Law:Planck's law is E = hf, where E is your energy in units of Joules, h is known as Planck's constant, in units of J*s and f stands for frequency, which is in units of inverse seconds or Hertz....
How do astronomers describe the shape of the universe, and what could it mean for the fate of the cosmos?When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The microwave sky as seen by Planck. This multi-frequency all-sky image of ...
A map of the background radiation left over from the Big Bang, taken by the ESA's Planck spacecraft, captured the oldest light in the universe. This information helps astronomers determine the age of the universe. (Image credit: ESA and the Planck Collaboration, CC BY-SA) This accidental ...
The energy of ordinary electromagnetic radiation won't do; its pressure is positive. The dark energy might be manifesting the optional cosmological constant allowed by the field equations of general relativity. But the magnitude of inferred from the observations is implausibly small by many orders 1...
What is the wavelength of an H atom {eq}(1.67 \times 10^{-27}\ kg) {/eq} if it is traveling at 700 m/s? Use {eq}6.626 \times 10^{-34}\ kg\cdot m^2/s {/eq} for Planck's constant. Division for ...
What is the energy of a single photon with a frequency of {eq}7 \times 10^8 {/eq} Hz. (hint Planck's constant = {eq}6.626 \times 10^{-34} {/eq}) Photon At the beginning of {eq}20^{th} {/eq}, Planck's gives a new theo...
