How Do You Calculate Frequency from Energy Using Planck's Constant?

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 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
