The lab experiment is repeated with the same two glass plates but with a different human hair. The sodium vapor lamp is replaced by a monochromatic light source that produces light of wavelength

?_air = 660 nm.

The separation between adjacent dark fringes is measured to be 0.485 mm. Calculate the diameter of the hair. (The length of the plates is 12.0 cm.)

Expert Solution

I have solved this question earlier with different figures. Please workout using yours figures. If you need any further help just PM me. If I have helped you please rate me 5 stars first (before you rate anyone else).

The lab experiment is repeated with the same two glass plates but with a different human hair. The sodium vapor lamp is replaced by a monochromatic light source that produces light of wavelength

?_air = 640 nm.

The separation between adjacent dark fringes is measured to be 0.450 mm. Calculate the diameter of the hair. (The length of the plates is 12.0 cm.)

answer

The first dark spot is at the zero location where the glass plates touch. To find the number of dark fringes after that, divide 12 cm by .45 mm

12/.045 = 266.7

Since you can't have a portion of a dark fringe, that means there are 266 additional dark fringes and therefore 267 bright fringes. The end with the hair must be a bright fringe to account for the .7

That will be the 266th bright fringe

Apply 2nt = (m + .5)wavelength

2(1)(t) = (267.5)(640 X 10^-9)

t = 8.56 X 10^-5 m (That is 85.6 um)

Two flat plates of glass with parallel faces are on a table, one plate on the other. Each plate is 11.0 cm long and has a refrac- tive index of 1.55. A very thin sheet of metal foil is inserted under the end of the upper plate to raise it slightly at that end, in a man- ner similar to that discussed in Example 35.4. When you view the glass plates from above with reflected white light, you observe that,...

1. In an experiment, you grow E. coli cells in the lab at different temperatures. After the growth, you isolate their cell membranes, perform complete hydrolysis of their cell membranes and isolate and quantify the percentages of different fatty acids in your final sample. How would you expect the fraction of myristic acid to change as you increase the temperature? 2. Succinyl-CoA is a negative regulator of α-ketoglutarate-dehydrogenase complex. Explain why this makes sense, and propose a possible mechanism for...

Two parallel conducting plates are oriented in an ? − ? coordinate system. The plates are separated by a distance ? = 0.05 ?, and the origin of the coordinate system is halfway between the plates. The plate separation is very small compared to the size of the plates. The left plate is at a potential ?L = 50 ?, and the right plate is at a potential ?R = 10 ?. 1. A proton at the origin begins at...
