T1 Flashcards
1
Q
How to calculate sinØ?
A
opposite / hypotenuse
2
Q
How to calculate path way difference= AB- A’B’?
A
AB-A’B’=d(sinØm+dsinØi)
Where Øi is positive, and Øm is negative if on the opposite side of the grading normal
3
Q
When we get constructive interference?
A
4
Q
How to calculate absorbance?
A
A=log(P0/P)=-logT
5
Q
How to calculate transmittance?
A
T=P/P0
where P is total light and P0 is light transmitande
6
Q
What is Beer-Lambert Law?
A
A=ε c l
7
Q
What is molar absorption coefficient?
A
It is a measurement of how strongly a chemical species absorbs light at a given wavelength. Units M-1 cm-1
