Question

Kim demonstrates to her father the movement and properties of longitudinal waves. They each hold one end of the spring (slinky). Kim quickly moves the spring forwards and backwards to the original position so that a range of pulses moves along the spring. It takes 1,8s for a wave from one end of the spring to the other end. The length of the spring is 6,3 m. .
1,8 calculate the speed of the waves in the spring
1,9 The distance from the middle of the first compression to the middle of the last compression is 5,75 m, as shown in the sketch. indicate that the wavelength of the waves in the springs is 1,92 m
1.10 calculate the frequency of the waves in the spring
1.11 calculate the period of the waves in the spring
1.12 what happens with the wave when it hits the fathers hand?

Answer 1

hi I just have one more question
2. 2.1 distinguish between a transverse wave and a longitudinal waves by completing the following table.
Properties__________________________ Transverse wave ____________________ Longitudinal wave
*direction of disturbance
*does it need a medium
*description of amplitude
*description of period
*description of frequency
*description of wavelength
*sketch of wave
*wave equation
*example(s)
