When a Metal Surface Is Illuminated with Light of Wavelength

Question 29

Short Answer

When a metal surface is illuminated with light of wavelength 437 nm,the stopping potential for photoelectrons is 1.67 V.(c = 3.00 × 108 m/s, When a metal surface is illuminated with light of wavelength 437 nm,the stopping potential for photoelectrons is 1.67 V.(c = 3.00 × 10<sup>8</sup> m/s, , , 1 eV = 1.60 × 10<sup>-19</sup> J,m<sub>el</sub> = 9.11 × 10<sup>-31</sup> kg) (a)What is the work function of the metal,in eV? (b)What is the maximum speed of the ejected electrons? , When a metal surface is illuminated with light of wavelength 437 nm,the stopping potential for photoelectrons is 1.67 V.(c = 3.00 × 10<sup>8</sup> m/s, , , 1 eV = 1.60 × 10<sup>-19</sup> J,m<sub>el</sub> = 9.11 × 10<sup>-31</sup> kg) (a)What is the work function of the metal,in eV?
