Hi.
there's physics test tomr and i've not studies for it yet. sian.
i dont get how the lens worked. what is focal point ? what is 2f>/< ?
why must we study all these? Its not like the light will disappear if we dont study them.
however, this is not an excuse to not study physics.
so oh well, gtg now. bye beautiful people:)
