The velocity of an electron that is emitted from a metallic surface by a photon is 3.6

Question:

The velocity of an electron that is emitted from a metallic surface by a photon is 3.6 * 103 km·s^–1.

(a) What is the wavelength of the ejected electron?

(b) No electrons are emitted from the surface of the metal until the frequency of the radiation reaches 2.50 * 10¹⁶ Hz. How much energy is required to remove the electron from the metal surface?

(c) What is the wavelength of the radiation that caused photoejection of the electron?

(d) What kind of electromagnetic radiation was used?
