When a sound wave passes from air into water do you expect the frequency wavelength to change?
The speed of the wave increases, the frequency remains constant and the wavelength increases. The angle of the wave also changes.
If wave speed remains constant what happens to the wavelength of the waves as the frequency?
they all have a direct relationship so one of the variables would have to change to effect the other
How does the speed of a wave affect its wavelength?
This can be answered using light or sound. Light will remain at a constant speed regardless of frequency or amplitude. Its shift in frequency (Doppler shift) is caused by the extreme distances the light had to travel to get here. Still it remains at the same speed. Sounds speed will change with local conditions. Also subject to an audible Doppler shift when a constant note is moved past you you can hear the pitch shift. The motion compresses the sound as it approaches and spreads it out as it moves away from you.

What is the name of a value that does not change?
A "constant"
