Chapter 27, Problem 54 GO Your answer is partially correct. Try again. A soap film (n = 1.33) is 464 nm thick and lies on a g

Answer 1

Answer #1

Using relation,

2 nt = λ (m + 0.5)

For m = 1,

2 x 464 x 1.33 = λ(1 + 0.5)

λ = 822.83 nm

For m = 2,

2 x 464 x 1.33 = λ(2 + 0.5)

λ = 493.7 nm

So, wavelength, λ = 493.7 nm (since lies between the given range)
