A laser’s power is given in mW. Wavelength of the light is also given. What is the energy and how many photons are emitted per second?
A laser’s power is given in mW. Wavelength of the light is also given. What is the energy and how many photons are emitted per second?
Determine the de Broglie wavelength for three items. A proton (velocity given), an electron (velocity given) and another item (mass & velocity given).
An electron’s postion is known within x meters. Determine the minimum uncertainty in its velocity. Next repeat with an atom of a given element.
If n = # and l = #, what is the orbital?
Complete the table with the number of radial nodes and the number of angular nodes in each orbital.
Four elements are given. Arrange them from smallest to largest atomic radius using the periodic table trends.
