Welcome to the forums, waleed123456. The second one is wrong.

As bhaisahab said, "What reading is?" is incorrect. Your first sentence is the correct construction of a sentence.
Also note the correct spelling of "difference".

I believe you could use these:

What is reading?
Do you know what reading is?
