A uniform monochromatic beam of light of wavelength `365xx10^-9`m and intensity `10^-8 W m^-2` falls on a surface having absorption coefficient 0.8 and work function 1.6 eV. Determine the number of electrons emitted per square metre per second, power absorbed per `m^2`, and the maximum kinetic energy of emitted photo electrons.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate the Energy of a Photon
The energy of a photon can be calculated using the formula:
\[ E = \frac{hc}{\lambda} \]
Where:
