Answer:
 1 * 10^-1 m

Explanation:
The given function is:
y = (3*10^8) / x
where:
y is the frequency
x is the wavelength

We want to find the wavelength at frequency 3 * 10^9
Therefore, all what we will do is substitute y with the given frequency and solve for x as follows:
y = (3*10^8) / x
3 * 10^9 = (3*10^8) / x
x = (3*10^8) / (3*10^9)
x = 0.1 which is equivalent to 1 * 10^-1 m

Hope this helps :)
