External Flash Question: Focal length for APS cameras

I assume all the flashes are for both full frame and APS.

Since the an APS camera just crops the full frame images, the focal length of the flash is the same for both. Am I right?

If it is true, then we get a "wider" (and probably better) lighting from the flash for an APS than for a full frame in a given focal length setting. The wideness is actually the same, but for the APS it's more than needed.

Thanks.
