When monochromatic light is incident on a photosensitive surface,the number of photoelectrons emitted per second from the surface is $n$ and the maximum kinetic energy is $K_{max}$. If the intensity of the incident light is doubled,then...

• A
  $n$ and $K_{max}$ will both be doubled.
• B
  $n$ and $K_{max}$ will both be halved.
• C
  The value of $n$ will be doubled,but the value of $K_{max}$ will remain the same.
• D
  The value of $K_{max}$ will be doubled,but the value of $n$ will remain the same.
