A plane water wave passes from deep water into a region of shallower water, causing it to refract. How do the speed, wavelength, and frequency of the wave change as it enters the shallower water?
The speed decreases, the wavelength decreases, and the frequency remains constant.
The speed decreases, the wavelength remains constant, and the frequency decreases.
The speed increases, the wavelength increases, and the frequency remains constant.
The speed remains constant, the wavelength decreases, and the frequency increases.
