Help! You are creating a transverse wave in a rope by shaking your hand from side to side...?

You are creating a transverse wave in a rope by shaking your hand from side to side. Without changing the distance that your hand moves, you begin to shake it slower and slower.


What happens to the frequency? What happens to the amplitude? What happens to the wavelength?


A. it increases


B. it decreases


C. it stays the same


D. need to know the exact change in speed





The amplitude would be C. The wavelength would be A. The frequency would be C or B?Help! You are creating a transverse wave in a rope by shaking your hand from side to side...?
The key word would be slower, this should tell you that whatever it is is happening less FREQUENTly, so frequency decreases. Wavelength and frequency are inversely related so if frequency decreases wavelength increases. The next key point is ';without changing the distance that your hand moves'; tells you the total distance (amplitude) that your hand makes is the same as before, so the amplitude must remain the same.
