To estimate how many visible light photons a 100 W light bulb emits per second, we can follow these steps: ### Step 1: Calculate the energy emitted as light Given that the efficiency of the bulb is 3%, we can calculate the energy emitted as light per second: \[ \text{Energy emitted as light} = \text{Total power} \times \text{Efficiency} = 100 \, \text{W} \times 0.03 = 3 \, \text{J/s} \] ...
