Stella [2.4K]3 years ago
6 0

Answer:

B

Explanation:

Because this oscillations occur when the restoring force is directly proportional to displacement, given as

F=-kx

Where k= force constant

X= displacement

78. A film of oil on water will appear dark when it is very thin, because the path length difference becomes small compared with
Hoochie [10]

To solve this problem it is necessary to apply the concepts related to the condition of path difference for destructive interference between the two reflected waves from the top and bottom of a surface.

Mathematically this expression can be described under the equation

\delta = 2nt

Where

n = Refractive index

t = Thickness

In terms of the wavelength the path difference of the reflected waves can be described as

\delta = \frac{\lambda}{4}

Where

\lambda = Wavelenght

Equation the two equations we have that

2nt = \frac{\lambda}{4}

t = \frac{\lambda}{8n}

Our values are given as

\lambda = 380nm \rightarrow Wavelength of light

n = 1.4

t = \frac{380nm}{8*1.4}

t = 33.93nm

Therefore the minimum thickness of the oil for destructive interference to occur is approximately 34.0 nm
