Answer : The frequency of this yellow light is, $5.172\times 10^{14}s^{-1}$

Explanation : Given,

Wavelength of yellow light = $580nm=580\times 10^{-9}m$

conversion used : $1nm=1\times 10^{-9}m$

Formula used :

$\nu=\frac{c}{\lambda}$

where,

$\nu$ = frequency of light

$\lambda$ = wavelength of light

c = speed of light = $3\times 10^8m/s$

Now put all the given values in this formula, we get:

$\nu=\frac{3\times 10^8m/s}{580\times 10^{-9}m}=5.172\times 10^{14}s^{-1}$

Therefore, frequency of this yellow light is, $5.172\times 10^{14}s^{-1}$
