Question
what is relationship between absorption and transmittance in
u.v.?
 Question Submitted By :: Rajesh
I also faced this Question!!     Rank Answer Posted By  
 
  Re: what is relationship between absorption and transmittance in u.v.?
Answer
# 1
absorption is inversely proportional to the transmittance.

A light is passed through the solution,if any absorption
take place means transmittance is zero.If any transmittance
takes place absorption is zero.

Answer
# 2
Absorption and transmittance have inverse logarithamic
relation.
for ex.
A perfectly black body have absorption 100% and
transmittance 0%.

  Re: what is relationship between absorption and transmittance in u.v.?
Answer
# 4
A = (1-Log T)

(Absorbace is equal to one minus log of Transmittance to
the base 10)

  Re: what is relationship between absorption and transmittance in u.v.?
Answer
# 7
Transmittance =(100-Absorbance)
If a compound has 100% absorbance it has 0% transmittance
 
Is This Answer Correct ?    9 Yes 1 No

Answer
# 8
The relations between A and T is:-
A=-log T
=-log (I/Io).
