Glass absorbs ultraviolet (UV) rays from the Sun. Would a fraction of the incident UV light be reflected from the air/glass boundary?

Respuesta :

Answer:

Yes

Explanation:

Any transparent surface in practical is neither a perfect absorber of electromagnetic waves neither a perfect reflector. Generally all the transparent surfaces reflect some amount of irradiation and the other parts are absorbed and transmitted.

That is given by as relation:

[tex]\alpha+\rho+\tau=1[/tex]

where:

[tex]\alpha=[/tex] absorptivity which is defined as the ratio of the absorbed radiation to the total irradiation

[tex]\rho=[/tex] reflectivity is defined as the ratio of reflected radiation to the total irradiation

[tex]\tau=[/tex] transmittivity is defined as the ratio of total transmitted radiation to the total irradiation
