Question

A laser is set up a distance of x away from a pair of narrow slits that are a distance d apart. When the laser is turned on, it shines through the two closely spaced slits, producing a characteristic pattern of alternating bright and dark regions on a wall a distance of L away from the slits. Listed below are five modifications that you could make to this experimental setup. Place each modification in the appropriate bin according to the effect it would have on the spacing between the bright spots on the wall. In each case, assume that everything else is held constant. Causes the spacing between the bright spots on the wall to increase. Causes the spacing between the bright spots on the wall to decrease. Has no effect on the spacing between the bright spots on the wall. increasing the distance L from the slits to the wall increasing the brightness of the laser light increasing the distance x from the laser to the slits increasing the wavelength of the laser light increasing the distance d between the two slits in the barrier

Explanation / Answer

1st bin increase L

2nd bin increase d

3 rd bin increasing brightness of laser ligh
