Please check out Carol's post, #134666. It is probable that
Dumbledore was actually hit with a nonverbal Impedimenta from Snape. 
Carol's post describes the effect of Impedimenta, and it sounds like 
what happened to Dumbledore. (The slow lowering to the ground may be 
another spell, perhaps the one Dumbledore used when Harry was 
attacked by Dementors while playing Quiddich.) Interestingly, JKR 
never describes the color of light associated with Impedimenta--I 
wouldn't be surprised at all if it were green.

An obvious question is, how can you verbalize one spell but cast 
another spell nonverbally? JKR may give us a foreshadowing of this 
when Harry *hears* the word "Expelliarmus" but *experiences* a 
Freezing Charm. Throughout the rest of the scene, Harry continues to 
hold his wand, so the Expelliarmus did not work on him. However, he 
does remain rigid and immobile--the result of a successful nonverbal 
Petrificus Totalus cast by Dumbledore.
