An incident radiation has a wavelength of 42.86 nm and is consequently enough to eject electrons through a retarding potential of 20.95 volts, so that they end up with a velocity of exactly 6.00 X 10^5 m/s. Calculate the work function of the particular metal. (Answer id electron volts)(adsbygoogle = window.adsbygoogle || []).push({});
