Question

Transmittance of the solution increases when
(i) path length decreases,
(ii) path length increases,
(iii) concentration increases, (iv) wavelength decreases​

Answer 1

Transmittance of the solution increases when path length decreases,

Answer 2

Answer:

option(i)-path length decreases

Explanation:

The ability of a material's surface to transfer radiant energy is measured by its transmittance. In contrast to the transmission coefficient, which is the ratio of the transmitted to an incident electric field, it is the percentage of incident electromagnetic power transmitted through a sample.

Internal transmittance is energy loss owing to absorption, whereas total transmittance is energy loss due to absorption, scattering, reflection, and other factors.

transmittance% =e^-(E*b*c)

where E=molar absorptivity coefficient

           b=path length of sample

           c=concentration of the  compound in solution
