In 1905, Albert Einstein studied the photoelectric effect, which is the ability of light to dislodge electrons from a metal surface, causing a current to flow between metal electrodes. 1st attempt Part 1 (1 point) I See Periodic Table See Hint Thin layers of potassium (Q = 3.68 X 10-19 )) and sodium (Q = 4.41 x 10-19 J) are exposed to radiation of wavelength 380 nm. The electrons emitted from K will have a higher velocity. Part 2 (1 point) See Hint Calculate the velocity of these electrons. The mass of an electron is equal to 9.10938 x 10-31 kg, the speed of light (c) is equal to 3.00 x 108 m/s, and Planck's constant is h= 6.626 X 10-34 Js. m/s
