Ireally need on this question!
the spectrophotometer really measures the percent of light that is transmitted through the solution. the instrument then converts %t (transmittance) into absorbance by using the equation you determined in the pre-lab section. if the absorbance of a sample is 0.85, what is the percent light transmitted through the colored sample at this collected wavelength?

we only used the spectrophotometer to measure the absorbance and never got any %t values. so i have to convert absorbance to transmittance. how do i do this with the given absorbance of 0.85?

14.12% the percent light transmitted through the colored sample at this collected wavelength.

Explanation:

Formula used to convert absorbance into transmittance is:

where,

A = absorbance of solution

T = Transmittance

= incident light

= transmitted light

Given = A = 0.85

Percentage of light transmitted to color solution:

14.12% the percent light transmitted through the colored sample at this collected wavelength.

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
