If a soap bubble is 115 nm thick, what wavelength is most strongly reflected at the center of the outer surface when illuminated normally by white light? assume that n = 1.33. express your answer to three significant figures and include the appropriate units.

nm

Explanation:

= Index of refraction of soap bubble  = 1.33

= thickness of the soap bubble = 115 nm = 115 x 10⁻⁹ m

= wavelength of light = ?

= order = 0

For reflection , the necessary condition is

nm

the answer is a)
