Physics: Soap bubbles can display impressive colors, which are the result of the enhanced reflection of light of particular wavelengths from the bubbles walls. For a soap solution with an index of refraction of 1.29, find the minimum wall thickness that will enhance the reflection of light of wavelength 709 nm in air.

The value is $t = 1.374 *10^{-7} \ m$

Explanation:

From the question we are told that

The refractive index is $\mu = 1.29$

The wavelength is $\lambda = 709 \ nm = 709 *10^{-9} \ m$

Generally the condition for constructive interference is

$2 * \mu * t = (n - \frac{1}{2} )\lambda$

At minimum thickness(t) the order of the fringe(n) will be equal to 1

$2 * 1.29 * t = (1 - \frac{1}{2} )* 709 *10^{-9}$

=> $t = 1.374 *10^{-7} \ m$

The answer is D. The scientific method involves developing a question to answer a hypothesis. It has to determine whether a hypothesis is true or not which would involve questions that can be answered through testing and observation of the subject.
