Question

LAB Waves and Sound 6.1 Pre-Laboratory Both a longitudinal and transverse wave on a slinky can be described by the equation $(x, t) = s"" cos(kx-ut) ill in the table below comparing the physical meaning of each term for both longitudinal and transverse slinky waves. Be sure to relate each term to the wave equation. Recall hat the motion of the slinky coils in the transverse wave is very simlar to the motion of air in a sound the motion of the slinky coils in the transverse wave is very similar to the motion of air in a sound wave. Transverse Longitudinal Amplitude The maximum displacement of a single coil from its equilibrium position is Sm Frequency single element A single coil oscillates back and forth with frequency as the wave travels down the length of the slinky. Frequency- wave Pulses' of a crowded coils will pass by a single point in space with frequency Wave Length The distance between two pulses as they travel down the length of a slinky ( 2m/ k). Speed - wave The speed at which a bunch of coils travels along the slinky depends on tension and composition of slinky. Speed - single element A single coil travels back and forth with speed 2, 133

Explanation / Answer

Transverse

Longitudinal

Amplitude

The maximum distance of a single coil from its equilibrium position is Sm

The maximum displacement of a single coil from its equilibrium position is Sm

Frequency single element

A single coil oscillates up and down with frequency as perpendicular to the direction of propagation of wave

A single coil oscillates back and forth with frequency as the wave travels down the length of the slinky

Frequency wave

Single coil on the slinky moves up and down by a single point in space with frequency

‘Pulses’ of a crowded coils will pass by a single point in space with frequency

Wavelength

The distance between two consecutive troughs or crests as it moves up and down to the length of the slinky

The distance between two pulses as they travel down the length of the slinky

Speed- wave

The speed at which a bunch of coils travels along the slinky,

V= f =/k

The speed at which a bunch of coils travel along the slinky

V= f =/k. It also depends on tension and composition of slinky

Speed- Single element

A single coil move up and down with the speed s(x,t)/ t

A single coil travel back and forth with speed s(x,t)/ t
