How to convert cm$^{-1}$ to eV? - Physics Stack Exchange
2018年8月21日 · a wave with a wavenumber of κ = 1cm−1 κ = 1 c m − 1 will have a photon energy of Ephoton = 1 8065.544 eV E p h o t o n = 1 8065.544 e V. (Or, in other words: you got the conversion factor backwards. This is the kind of catastrophic mistake that you can easily get sucked into by being sloppy with your units and pretending that you can ...
Why does this paper use 1/cm for units of frequency?
2018年7月17日 · People working in the infrared or optical region tend to sometimes, depending on what school of thought they come from, use a unit called wavenumber, which is the reciprocal wavelength in centimeters, 1 λcentimeter 1 λ c e n t i m e t e r. This is still a frequency, but instead of oscillations per second, it is oscillations per centimeter.

Conversion formula between attenuation coefficient (cm^-1) and …
2019年10月13日 · So, I was presented in class the fact that (at least in Ultrasound), attenuation coefficients $\mu$ can be expressed in units $\text{dBcm}^{-1}\text{MHz}^{-1}$ as opposed to the form I was used to; simply $\text{cm}^{-1}$. For a sanity check, I decided I wanted to work out a formula to convert from one to the other.

Convert units from cal cm^-1 day^-1. to Wm-2 - Physics Stack …
1 day = 24 × 60 × 60 s = 86, 400 s, and 1 day = 24 × 60 × 60 s = 86, 400 s, and. 1 cm = 0.01 m 1 cm = 0.01 m. and just plug the numbers in: 1 cal cm−2 day−1 = 4.18 J (0.01 m)2 × 86400 s ≈ 0.48 W m−2. 1 cal cm − 2 day − 1 = 4.18 J (0.01 m) 2 × 86400 s ≈ 0.48 W m − 2. Easy!
Two values of Rydberg Constant - Physics Stack Exchange
2024年5月27日 · In my textbook I came across two values of Rydberg Constant: R Rh = 109677 cm−1 = 2.18 ×10−18 J R = 109 677 c m − 1 R h = 2.18 × 10 − 18 J. when we are calculating energy of the stationary state. So can anyone clear this confusion of mine?
