Question 44
PHMCQ2 marksNeeds review
Young’s double slit experiment is performed using a beam of
(fullerene) molecules, each molecule being made up of 60 carbon atoms. When the slit separation is 50 nm, fringes are formed on a screen kept at a distance of 1 m from the slits. Now, the experiment is repeated with
molecules with a slit separation of 92.5 nm. The kinetic energies of both the beams are the same. The position of the
bright fringe for
will correspond to the
bright fringe for
. What is the value of
(rounded off to the nearest integer)?Your answerChoose one option.
