5.2. Mike produces 5 full waves in 2 s. What is the frequency of the wave?
Mike pushes and pulls the slinky spring at a lower frequency.
5.3 How will the wavelength of the wave change? Explain.
5.4 How will the speed of the wave change? Explain.
The frequency of the wave can be calculated by dividing the number of waves (5) by the time taken (2 s):
Frequency = Number of waves / Time taken = 5 / 2 = 2.5 Hz
5.3 If Mike pushes and pulls the slinky spring at a lower frequency, the wavelength of the wave will increase. This is because wavelength and frequency are inversely proportional, according to the equation: wavelength = speed / frequency. As the frequency decreases, the wavelength will have to increase in order to maintain the same speed.
5.4 The speed of the wave will not change if Mike pushes and pulls the slinky spring at a lower frequency. The speed of a wave is determined by the medium it is traveling through and is not affected by the frequency of the wave. So, regardless of the frequency, the speed of the wave will remain the same.
