Please help me with this question :
A soap bubble has the index of refraction n = 1.33. There is air both inside and outside
the bubble.
a/ What wavelength (in air) of visible light is most strungly reflected from a point on a soap bubble where
its wall is 290 nm thick? To what color does this correspond?
b/ Repeat part a/ for a wall thickness of 340 nm. What is your observation about the two answers a/ and b/?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply. the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
