Transmittance is given as T = P/Po. If Po is the power incident on the sample, what does P represent?
A. Radiant power transmitted by the sample
B. Radiant power absorbed by the sample
C. Sum of powers absorbed and scattered
D. Sum of powers transmitted and reflected
Answer:A
Transmittance is given as T = P/Po. If Po is the power incident on the sample, what does P represent?
A. Radiant power transmitted by the sample B. Radiant power absorbed by the sample C. Sum of powers absorbed and scattered D. Sum of powers transmitted and reflected
Explanation: P represents radiant power transmitted by the sample. Transmittance is the ratio of radiant power transmitted by the sample to the radiant power that is incident on it.
