Which statement correctly describes the relationship between wavelength and frequency?

• As wavelength decreases, the frequency increases because more waves pass a point each second.

• As wavelength decreases, the frequency increases because fewer waves pass a point each second.

• As wavelength increases, frequency increases because more waves pass a point each second.

• As wavelength increases, frequency increases because fewer waves pass a point each second.
