Question: During an experiment $6$x$1014$ Hz light shines on a metal plate and the Photoelectric Effect occurs. It is determined that the stopping potential is $1\mathrm{.}9$ V$.$ Determine the momentum $($in Ns$)$ a photon has at the given frequency & determine the cutolf frequency $($I$.).$During an experiment $6$x$1014$ Hz light shines on a metal plate and the Photoelectric Effect occurs.
