Observing Wave Pulses

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 …

…smaller than the inverted pulse. Q14 - If the case is light - dense - fixed, the pulse, after reaching the boundary will return becoming inverted. The transmitted pulse will reduce in size and then reflect inverted at the fixed end. If the arrangement of the spring is going from dense to light, then the pulse will not be inverted when it is reflected at the boundary with the transmitted wave being larger and quicker.
