1 февр. 2018 г. · The threshold wavelength is that wavelength at which a photon striking the electron will impart to it just the work function and nothing more. |
3 дек. 2015 г. · Okay so here's how it works. · Kinetic energy = photon energy - work function · Ek = hf - phi · That equation traces a line such as · y = mx + b. |
22 июл. 2017 г. · The threshold wavelength is that wavelength at which a photon striking the electron will impart to it just the work function and nothing more. |
24 июл. 2018 г. · The threshold wavelength is that wavelength at which a photon striking the electron will impart to it just the work function and nothing more. |
21 июл. 2018 г. · KE= hc/lambda- W KE=0, so, hc/lambda= W Call lambda “L”, then L=hc/W=6.62E-34(3E8)/2(1,6E-19) L=6.21E-7m or 621 nm. |
21 июл. 2018 г. · Threshold wavelength is the maximum wavelength of incident photon/radiation at which electron ejection from the metal can take place. |
