Default 35 mm lens: focal length

Hi, I have a bit of a n00b question.

I have a Carl Zeiss Jena lens on my camera and I'd like to know the focal length of the lens. I'm not familiar with the notation: 2.8/50.

Enlighten me?

Thanks a lot,
Aleksiina

It appears the focal length is 50mm, what is commonly refered to as a normal
lens which is in between a wide angle and a short telephoto. The 2.8 is
probably the aperture # - that is the size of the opening that lets in the
light.
