CONCEPT:
λ = h/ √ 2mev
h = 6.63 x 10-34 me = mass of an electron v = potential difference EXPLANATIONS: we know Plancks constant (h) = 6.63 x 10-34. Volt = 100 v Mass of electron (me ) = 9.1 x 10-31.. Putting all these values in λ = h/√ 2mev 6.63 x 10-34/√ 2 x 9.1 x 10-31 x 100 0.123 nm Option 1 is correct. India’s #1 Learning Platform Start Complete Exam Preparation
