A green bulb and a red bulb are emitting the radiations with equal power. The correct relation betwe — Atomic Structure Chemistry Question

💡 Solution & Explanation

Power $P = n \times \frac{hc}{\lambda}$. Since power is equal, $n \propto \lambda$. The wavelength of green light is less than that of red light ($\lambda_g < \lambda_r$), so $n_g < n_r$. Therefore, correct answer is B.
