Text Solution

AI Generated Solution

To solve the problem of finding the number of photons emitted by a monochromatic source in 5 minutes, we can follow these steps: ### Step 1: Convert the wavelength from nanometers to meters The given wavelength is 500 nm. To convert this to meters: \[ \text{Wavelength} (\lambda) = 500 \, \text{nm} = 500 \times 10^{-9} \, \text{m} \] ...
