Per NCERT eqn 2.5, the relation between the frequency ν, wavelength λ, and the speed of light c in vacuum is which equation?
Ac = ν / λ
Bc = ν + λ
Cc = λ²/ν
Dc = ν λ
Answer & Solution
Correct answer: D. c = ν λ
Per NCERT eqn 2.5, all EM radiation in vacuum travels at c = ν λ where c = 3.0 × 10⁸ m/s.
