Observing Wave Pulses

EXPERIMENT 15
PART 1 - Transverse Wave Pulses
Q1 - As the pulse travels down through the spring, its, size and amplitude is reduced - the sizes of the waves are much smaller as the forces become weaker (losing energy) as the distance from the point of initiation is increased.
Q2 - Pulses do not 'catch up' with one another in transverse waves. They either meet at a certain point momentarily or pass through each other and continue on their way as if nothing has happened.
Q3 - As the tension of a spring is increased, the speed of the pulse is also increased meaning that the pulse will travel through the spring quicker if the spring is held more taut. A tighter spring also may also decrease the amplitude (dependent of the force).…
