Physics · Dual Nature of Radiation and Matter
जब एक धात्विक सतह को तरंगदैर्घ्य λ के विकिरण से रोशन किया जाता है, तो निरोधी विभव (stopping potential) V होता है। यदि उसी सतह को तरंगदैर्घ्य 2λ के विकिरण से रोशन किया जाता है, तो निरोधी विभव V4 हो जाता है। धात्विक सतह के लिए देहली तरंगदैर्घ्य (threshold wavelength) क्या है?
