In a double-slit experiment, electrons are fired at an opaque barrier having two small slits, and a screen beyond the barrier records where the electrons hit. after many electrons are fired, what is observed on the screen? in a double-slit experiment, electrons are fired at an opaque barrier having two small slits, and a screen beyond the barrier records where the electrons hit. after many electrons are fired, what is observed on the screen? the pattern observed indicates that electrons struck the screen in alternating bands across the screen. the pattern observed indicates that electrons struck only the areas of the screen directly across from the two slits. the pattern observed indicates that electrons struck only the center of the screen. the pattern observed indicates that electrons struck the screen directly across from the two slits and the center of the screen.

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
