two rays of different wavelength will generate the same electric current ?

Hi,

I have 2 different light rays which have different wavelengths (for
instance one is red and the other is green).

I'm sending these rays to 2 photodiodes.

Is the electric current generated by those photodiodes the same? Are
there any differences (power, intensity) ?


thanks,
laura

1. Photodiodes have different sensitivities (efficiencies)
at different wavelengths.

2. Photons of different wavelengths have different amounts
of energy.

3. Intensity depends upon the *number* of photons involved,
not just the energy per photon.

Now, given the above, what do you think?
