If 5% of the energy supplied to an incandescent light bulb is radiated as visible light, how may visible light photons are emitted by a 100W bulb? Assume the average wavelength of all visible photons to be `5600Å`. Given `h=6.25xx10^(-34)Js`.

Explanation

To solve the problem of how many visible light photons are emitted by a 100W incandescent light bulb that radiates 5% of its energy as visible light, we can follow these steps:

### Step 1: Calculate the total power radiated as visible light
The power radiated as visible light is given as 5% of the total power of the bulb.

\[ \text{Power radiated as visible light} = 0.05 \times 100 \text{ W} = 5 \text{ W} \]
