Question

Part A How far from the contact line wil green ight (wavelength 553 nm) first have its reflection enhanced? Two fat glass plates are on a table, one plate on the other. Each plate is 55.0 mm long and has a refractive index of 1.55. A very thin sheet of metal foil is nserted under the right end of the top plate, forming a triguar wedge air gap. When iewed from above, violet light (having wavelength 404 nm has ts first enhanced reflection at 1.20 mn from the le#t edge (where the plates contact) greo, 1 -1.64 mm Submit My Answers Give Up Correct Part B How far from the ine of contact the violet ight's reflection next be enhanced (violet's bright #2)? vialet, 2 3.60 mm Submit My Answers Give Up Correct Part C How many iolet bright lines are visible along the plate? My Answers Give Up Submit

Explanation / Answer

use 2t=m

where

t is the thickness of the paper,

m is the number of bands and

is wavelength

so m = 2t/L

m = 2 *55*10^-3/(404 *10^-9)

m = 272277 lines
