We have been given that the inverse variation shows the relationship between wavelength in meters, x, and frequency, y. We are asked to find the wavelength for radio waves with frequency
.
To find the required wavelength, we substitute in our given equation and solve for x as:
We can see that both numerator and denominator has 3, so we can cancel it out.
Using quotient rule of exponents , we will get:
Therefore, the wavelength for radio waves would be meters and option B is the correct choice.
