Question: Question 9 (1 point) Light is shining on a metallic surface causing electrons to be ejected. Increasing the frequency of light: O causes ejected electrons

Question 9 (1 point) Light is shining on a metallic surface causing electrons to be ejected. Increasing the frequency of light: O causes ejected electrons to have more kinetic energy causes ejected electrons to have less velocity causes even more electrons to be ejected causes no change to the ejected electrons or to the number of ejected electrons O) none of the above Question 10 (1 point) The value of 6.63 x 10 34 J's is known as Threshold frequency Photon energy Planck's constant 1 Electron-volt
