-
C.
speed decreases
-
D.
speed remains the same but its frequency and wavelength change
-
E.
speed increases but its frequency and wavelength decreases
Correct Answer: Option B
Explanation
Speed: The speed of sound is greater in water than in air.
Frequency: The frequency of the sound wave remains constant when it transitions between different mediums.
Wavelength: Since the speed increases while the frequency remains constant, the wavelength must increase as well.
