(Physics 2019-20 2Marks AMU +2) 🎁Question 9- An electron, an alpha particle and a proton have the same kinetic energy. Find ratio of de Broglie wavelength? (Physics 2019-20 2Marks AMU +2) Ruhul Amin Alig 💥de Broglie wave has many equation:1. λ= h/mv2. λ=h/√2mk3. λ=h/√2mvhere we will use 3. eqi.e. λalphaλproton=mprotonmalphamalpha=4mprotonSo,λalphaλproton=mprotonmalpha=14=2 Facebook Twitter Whatsapp Newer Older
