4. A longitudinal wave moves along a slinky spring. At the moment shown below, position A and B are the centers of a compression and a rarefraction respectively and are 24cm apart.
4.1 what is the wavelength of this wave?
4.2 it takes 1,5 s for a compression to move from A to B.
4.2.1 calculate the speed of the wave
4.2.2 calculate the frequency of the wave.
4.1 The wavelength of the wave can be calculated by measuring the distance between two consecutive points of the same phase. In this case, the distance between position A and position B is the wavelength.
Wavelength = 24 cm.
4.2.1 The speed of the wave can be calculated using the formula:
Speed = Wavelength / Time
Speed = 24 cm / 1.5 s = 16 cm/s
Therefore, the speed of the wave is 16 cm/s.
4.2.2 The frequency of the wave can be calculated using the formula:
Frequency = 1 / Time
Frequency = 1 / 1.5 s = 0.67 Hz
Therefore, the frequency of the wave is 0.67 Hz.
