You need more information: the length of a side.
Then, since the diagonals bisect one another at right angles, you can use Pythagoras's theorem to calculate their lengths.

The diagonals are perpendicular, but not necessarily congruent.
It has two diagonals, and they are perpendicular to each other.
Oh, dude, it's like the diagonals in a rhombus are totally those lines that connect the opposite corners. They're like the fancy crossroads of the rhombus world, making all those right angles and stuff. So yeah, if you ever need to find them, just look for those lines that cut the rhombus in half diagonally.
Square, rhombus or a kite.
Yes, they are perpendicular and intersect at their midpoints. The difference between diagonals in a rhombus as opposed to a rectangle or square is that the diagonals are not of equal length.
