(5%) Problem 12: A thin layer of oil with index of refraction no 1.47 is floating above the water. The index of refraction of water is n 1.3. The index of refraction of air is na 1. A light with wavelength 375 nm goes in from the air to oil and water Otheexpertta.com 83 25% Part (a) Express the wavelength of the light in the oil. io. in terms of i and no Grade Summary Deductions 12% 88% Potential s 9 HOME Submissions Attempts remaining: 3 60% per attempt) detailed view 6% P S VO BACKSPACE DEL CLEAR Hints 1 for a 0% deduction. Hints remaining 0 Feedback: 0% deduction per feedback. -The required equation is the basic definition ofwavelength in a medium A 25% Part (b) Express the minimum thickness of the film that will result in destructive interference, t in terms of o. A 25% Part (c) Express t in terms of and n A 25% Part (d) Solve for the numerical value of t an in nm.Explanation / Answer
a)
lambda not = lambda /n0
b)
for destructive interference
2tno = m xwavelength
m = 1 for mionimum
c)
t = wavelength /2n0
d)
t = 127.55nm
