Conversion of Light to a Energy or Force

In summary, the individual is attempting to convert a light source's intensity (measured in photons/cm^2/sec) into energy or force. They have tried using Planck's constant but are uncertain if this is the correct approach. They have a specific wavelength and are trying to calculate the energy or force for a light flash lasting 100 milliseconds with a stimulus intensity of 10^10.4 photon/cm^2/sec. They have searched for equations to use and have found information on calculating the energy of a photon, but are unsure how to apply this to their specific problem. They also mention trying to calculate force by multiplying the energy by the pathlength and time of the light stimulus.

I am looking to convert a light source (photons/cm^2/sec) to a energy or force. I have tried using Planck's but I'm not sure if this is in the right direction.

Any help greatly appreciated.

welcome to pf!

hi mariosphysics! welcome to pf! :smile:

you'll need to know the wavelength :wink:

ok i have a wavelength at 530 nm. I am trying to calculate the energy or force for a light flash (100ms). And a stimulus intensity such as 10^10.4 photon/cm^2/sec.

Is this possible? I do not know where to start. I was trying to convert to candela. But I could not find any equations to use.

hi mariosphysics! :smile:

(just got up :zzz: …)

google "energy of a photon" for lots of cool sites

for example, http://www.pveducation.org/pvcdrom/properties-of-sunlight/energy-of-photon" :wink:

Tiny-tim,

I understand how to calculate the energy of the light now. But how can I calculate it for the light flash or stimulus intensity such as 10^10.4 photon/cm^2/sec.

Or when I calculate energy of a photon (E) and then divide by the stimulus intensity to get: Joules/cm^2/sec. Does this make sense?

and then to get force I can multiply by the pathlength and time of light stimulus?

thanks for your help

hi mariosphysics! :smile:

sorry, i don't see what you're getting at :confused:

can you give a specific problem as an example, and say what's worrying you about it?
