JEE Main 2025 Chemistry question
Heat treatment of muscular pain involves radiation of wavelength of about 900 nm. Which spectral line of H atom is suitable for this ? Given: Rydberg constant cm⁻¹, h = J s, c = m/s)
Answer: (1)
Solution
Using Rydberg equation with λ=900nm gives , satisfied by n₁=3, n₂=∞ (Paschen series).
