Water waves in a ripple tank travel from deep water into shallow water, causing them to refract.
Which statement correctly describes what happens to the waves as they enter the shallow water?
Their speed decreases, their frequency remains constant, and their wavelength decreases.
Their speed decreases, their frequency decreases, and their wavelength remains constant.
Their speed increases, their frequency remains constant, and their wavelength increases.
