Abstract

To measure the transmittance of drinking water, 2W LED light, Theremion_Spectrometer and diffraction grating are used. The research area is Nisi located in
Baglung district, Nepal. The observation is taken 9 sample of drinking water taken from different sources of Nisi. The observation shows that the
transmittance of drinking water taken from Kanabazer, Jiba Khola, Jiri, Jajir, Khahare Khola, Bhalu Khola and Nisi Khola is high. In addition, the absorbance
of drinking water taken from Khar Chowar is higher than other. The transmittance of the sample ranges from 32% to 100% while absorption coefficient
0.034 × 102
