When the One was destroyed, immediate effects were observed. Sauron's spirit was irreparably maimed, Barad-dûr, made with the One, collapsed, and the Nazgûl fell from the sky in ruin. Since those events were not gradual, why would the Three's fading be any different?

You might be right about the Three immediately becoming powerless after the one ring was destroyed, however if they were then how did Galadriel create that last parting flash of light from her ring in display to Frodo? It's true she was a powerful sorceress of sorts so I suppose creating a flash of light would not prove to difficult for her, but still it makes you wonder.
