### Ryberg's Constant

Hi everyone, I looked up Rydberg's constant in google and it gave me a different number from the constant that Dr. Lavelle has on his constants sheet... which one should I be using in my calculations? And what are the units for the Rydberg constant?

Most constants will be given to us for the tests so just use whatever is on the sheet.

I would use the one provided on the constant sheet and it probably have the units for it on there as well.

The constant listed on Lavelle's sheet is R=3.28984 * 10^15 and it's units are Hz.

I would rely more on what Dr. Lavelle has used in class/has provided for us on the constants sheet (R = 3.28984 × 10^15 Hz or 1/s). The Rydberg's constant on Google has a different unit (1/m) and would possibly interfere with the calculations Dr. Lavelle has taught us.

Do use the one given by Dr. Lavelle. Since Rydberg's constant is frequency, the unit is s^-1 or Hz.

### Re: Ryberg's Constant

I think there are two ryberg constants, one that is frequency (m/s) and one that is inverse wavelength. You can derive one from the other using the speed of light = frequency * wavelength equation.
