Interpretation Introduction

Interpretation:

The reflection loss when a radiation ray passes through an empty quartz cell should be calculated.

Concept introduction:

When a beam of radiation passes through two medias with different refractive indexes, a fraction of the beam reflected at interface. The refraction loss is expressed as follows,

lrl0=(n2n1)2(n2+n1)2Where,l0=intensity of the incident beamlr=reflected intensityn2, n1=refractive indexes of the two media

A certain half-reaction has a standard reduction potential Ered +1.26 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box.. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper limit, check the "no" box. yes, there is a minimum. 1 red Πν no minimum Oyes, there is a maximum. 0 E red Dv By using the information in the ALEKS…
