AI Thread Summary
To calculate frequency from energy using Planck's constant, the equation E=hv is essential, where E represents energy, h is Planck's constant, and v is frequency. For an energy value of 3.5 x 10^-14 joules, the frequency can be determined by rearranging the formula to v = E/h. Substituting the given values, v can be calculated using h = 6.63 x 10^-34 joule-seconds. This approach directly links energy and frequency, illustrating their proportional relationship. Understanding this formula is key to solving the problem effectively.

Read my Journal nd hlp. calculating frequency

--------------------------------------------------------------------------------

I have a problem that states as follows:

Calculate the frequency (in Hz) of energy of 3.5 x 10^-14 joules. (c=3.00 x 10^8 m/s; h=6.63 x 10^-34 joule-seconds)

I need help in setting this problem up. I found the equation E=hv, where E= the increase of energy, h= Planck's constant, and v= the freqency of light which increases propportionally with an increase in energy.

I am going crazy and just don't get it...

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
