Per NCERT eqn 2.6, Planck's quantum hypothesis (1900) states that the energy of a quantum of radiation is which expression?
AE = h ν, with h = 6.626 × 10⁻³⁴ J s
BE = mc²
CE = h / ν
DE = ½ m v²
Answer & Solution
Correct answer: A. E = h ν, with h = 6.626 × 10⁻³⁴ J s
Per NCERT eqn 2.6, Planck's E = h ν explains black-body radiation. h = 6.626 × 10⁻³⁴ J s.
