Bohr vs Speed of Light Equation

Postby Perla Cervantes_1G » Fri May 04, 2018 4:38 pm

How do you know when to use the Bohr equation vs the Speed of Light equation when solving for frequency?

Hi,
Both are good, it just depends on what information you are given. Typically, questions about the relationship between wavelength and frequency are best solved with c=lambda*nu. And questions about the energy of a photon are best solved with E=h*nu.

Typically, looking at the values you already have really helps. For example, if all you have is the wavelength, and the question mentions light, you would use the speed of light equation. If the question asks for frequency, and instead gives you the energy, then you can use the Bohr frequency equation.

What really helps me solving problems and deciding between the bohr and the speed of light equation Is by examining what the question is asking, such as in terms of units. for example for solving for wavelength, you could use c=(lambda)(wavelength).
