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?
The frequency is how often you shake your hand up and down. That goes down in this case, because they say so. The wavelength gets longer, but you have to know what happens to wave speed to say how much. The wave speed depends upon how tightly the rope is held (the tension).
