What can you say about$$ light reflected from the two surfaces of a soap bubble $($ air to flim; and film to air$),$ for a film that is very very thin $($ less than a fraction of a wavelength of light$)$

Group of answer choices

they are $180$ degrees out of phase and result in no reflected light from the film

they are a quarter a wave out of phase that results in circularly polarized light

they are in phase and results in no reflection of light from the film

they are in phase, and results in a bright reflection from the film
