You find wavelength from knowing the wavespeed and frequency.

#### Explanation:

Happily, they gave you the frequency and the wavespeed is the same for all e-m waves (at least in a vacuum, which is close enough for us) at $3 \times {10}^{8}$m/s

$\lambda = \frac{v}{f}$

$\lambda = \frac{3 \times {10}^{8}}{590000}$

$\lambda = 508.47 m$

Given that you were only given two significant figures in the data, you should quote the same precision in your answer so I’d say 510m.
