Thaum qhov xwm txheej wavelength yog lamda, nres muaj peev xwm yog 3V_0.
Kev sib raug zoo ntawm kev txwv tsis pub muaj peev xwm thiab wavelength yog dab tsi?
Given: Stopping potential=Vs=2 V , wavelength of events light=λ=2000 Å=2000 x 10 -10 m, ceev lub teeb=c=3 x 10 8 m/s, Planck's tas li=h=6.63 x 10-34 Js, Charge on electron=e=1.6 x 10- 19 C.
Thaum lub teeb ntawm wavelength lambda tshwm sim ntawm cov hlau nto qhov chaw nres tsheb?
Thaum lub teeb ntawm wavelength lambda tshwm sim rau ntawm qhov chaw hlau, txwv tsis pub muaj peev xwm pom tias yog x. Thaum lub teeb ntawm wavelength nlambda tshwm sim ntawm tib qhov chaw hlau, txwv tsis pub muaj peev xwm pom tau tias yog (x) / (n + 1).
Thaum qhov xwm txheej wavelengths yog Lambda thiab Lambda 2 lub zog kinetic?
Lub KE ntawm photoelectrons yog E thaum qhov xwm txheej wavelength yog (lamda) / (2). Tus KE yuav 2E thaum qhov xwm txheej wavelength yog (lamda)/(3).
Lub cim ntawm kev tso tseg muaj peev xwm yog dab tsi?
Kev txwv tsis pub muaj peev xwm yog qhov txiaj ntsig ntawm kev rov qab muaj peev xwm sib txawv ntawm ob daim phiaj uas tsuas yog txaus los nres lub zog tshaj plaws photoelectrons tawm. It is denoted by " Vo ".
