Answer:

89.5 Hz

Explanation:

The relationship between the frequency and the wavelength is given by the following formula:

[tex]\lambda = \frac{c}{f}\\\\[/tex]

where,

f = frequency

c = speed of light

λ = wavelength

Since the speed of light is constant. Therefore the formula suggests an inverse relationship between the frequency and the wavelength. Hence, the station with the lowest frequency will have the longest wavelength.

Therefore, the answer is:

89.5 Hz
