Interpretation Introduction

(a)

Interpretation:

The thickness of dielectric layer needs to be determined when the interference filter is of first-order.

Concept introduction:

Calculation of the thickness of the dielectric medium is done by the following formula-

λ=2dnn

And the relationship between wavelength and wave number will also be used:

λ=1v¯

Interpretation Introduction

(b)

Interpretation:

Wavelengths transmitted from interference filter at different orders needs to be determined.

Concept introduction:

Following formula will be used for the calculation of wavelength at different order of interference filter-

λ=2dnn

The abundance of ozone is typically inferred from measurements of UV absorption and is often expressed in terms of Dobson units: 1 DU is equivalent to a layer of pure ozone 103 cm thick at 1 atm and 0°C. Given a molar absorption coefficient of 476 dm³ mol 1 cm 1, compute the absorbance of UV radiation for the ozone values shown below. (a) 320. DU (a typical value) mol-1 4.0 15.2 x (b) 150. DU (a value reached during seasonal Antarctic ozone depletions)
Below are some common interferences that may be encountered in atomic absorption spectroscopy: (i) (ii) In flame AA with a hydrogen/oxygen flame, the absorbance for iron decreased in the presence of large concentration of sulfate ions. Suggest an explanation for this observation. Give a reason as to why excess strontium or lanthanum ions are always added in the analysis of calcium in flame AA using a hydrogen/oxygen flame.
(iii) You wish to determine the fluorescence lifetime of your sample using Time Correlated Single Photon Counting, TCSPC. Draw a sketch showing the layout and principal components of a suitable setup and explain the basis of the technique.
