λ = wavelength Wave Formula Derivation The derivation of the wave equation certainly varies depending on context. There is a particular simple physical setting for the derivation. Moreover, this setting is that of small oscillations on a piece of string in accordance with theHooke’s law. One ...
Statement : wavelength of (I) line of Humphry series is more than (I) line of Lyman series in H-atom Explanation :ΔE=hcλ. View Solution The wavelength ofHαline in Balmer series is View Solution Ratio of the wavelengths of line of Lyman series and first line of Balmer series is. ...

The wavelength required to break a chemical bond depends on the bond's dissociation energy. The energy of a photon needed to break a bond can be calculated using the formula \(E = \frac{hc}{\lambda}\), where \(E\) is the bond dissociation energy, \(h\) is Planck's co...
Analytical chemistryinvolves the analysis of chemicals, and includes qualitative methods like looking at color changes, as well as quantitative methods like examining the exact wavelength(s) of light that a chemical absorbed to result in that color change. ...
In chemistry, absorptivity is more accurately calledmolar absorptivity. This is the measurement of how muchelectromagnetic energya chemical will absorb, depending on the energy's wavelength. For molar absorptivity, the Beer-Lambert Law plays an important role. This law states that the amount of ligh...
