Canon EF 17-40 f/4L USM

I realize this is a question best answered by taking a photograph class and thats coming, but intill then....I was looking at the lense to go with a digital rebel and Im confused. The designations mean that it zooms from 17mm-40mm Right?

Or is it it can take a photo 17mm wide and up to 40MM long.

I get confused between zoom lenses and wide angle lenses that the description says this is?

Any one can feel free to drop some knowledgle

Thanks

Correct. The lower the number, the wider the field of view.
