Question

Consider a soap bubble ( both side of film is air) of thickness d and n = 1.5. Light of λ = 600 nm is incident on the bubble. Which values of d produce destructive interference?

Answer 1

Answer #1

For destructive interference

We know that 2d=n×lambda

2d=1.5×600

d=200nm

So d is 200nm produce destructive interference.

Answer 2

PROBLEM (a) Calculate the minimum thickness of a soap-bubble film (n 1.33) that will result in constructive interference in the reflected light if the film is illuminated by light with wavelength 602 nm in free space. (b) Recalculate the minimum thickness for constructive interference when the soap-bubble film is on top of a glass slide with n = 1.50 STRATEGY In part (a) there is only one inversion, so the condition for constructive interference is 2nt (m 1/2) The minimum...
