The correct answer is **always**.

According to the wave equation \( v = f \lambda \) (where \( v \) is the wave speed, \( f \) is the frequency, and \( \lambda \) is the wavelength), if the speed of the wave remains constant and you increase the wavelength (\( \lambda \)), the frequency (\( f \)) must decrease.
