The speed of light is 3 × 10° m/s and Planck's J.s. -34 constant is 6.63 × 10° Answer in units of eV. What is the threshold frequency for potas- sium? Answer in units of Hz.Plz solveWhich of the following statements are true? Choose all that apply. A photon has kinetic energy. O Electrons have a positive charge. If photon A has a larger momentum than photon B, photon A must be moving faster than photon B. Hotter objects have a larger peak frequency. Increasing the light intensity on a piece of metal will increase the maximum KE of the ejected electrons (assuming f > fo). If an electron drops down to the ground state, a photon will be emitted.
