Band Gap by UV-Visible Spectroscopy | Absorption | Transmission | Semiconductor Phy | B. Tech (Phy)

in this video we have discussed about what is absorbance, transmittance and the relationship between them. Absorption coefficient is also discussed. Towards the end we have explained the important relation in UV Vis spectroscopy by using Tauc’s formula. #Lecture_Series_SemiconductorPHYSICS Link of more RELATED videos : 1.
