Physics · Dual Nature of Radiation and Matter
जब तरंगदैर्ध्य λ का प्रकाश एक प्रकाश-संवेदी सतह पर आपतित होता है, तो निरोधी विभव (stopping potential) V होता है। जब उसी सतह पर तरंगदैर्ध्य 3λ का प्रकाश आपतित होता है, तो निरोधी विभव V/6 होता है। सतह के लिए देहली तरंगदैर्ध्य (threshold wavelength) कितनी होगी?
