Calculate the number of photons emitted in `10` hours by a `60 W` sodium lamp (`lambda` of photon `= 5893 Å)`

Explanation

To solve the problem of calculating the number of photons emitted by a 60 W sodium lamp over 10 hours with a wavelength of 5893 Å, we can follow these steps:

### Step 1: Convert Time from Hours to Seconds
First, we need to convert the time from hours to seconds since power is given in watts (joules per second).

\[ \text{Time (in seconds)} = 10 \text{ hours} \times 60 \text{ minutes/hour} \times 60 \text{ seconds/minute} = 36000 \text{ seconds} \]
