The table shows information about four waves. Which wave has the lowest frequency?
L: 120 (m) 600 (m/s)
M: 150 (m) 600 (m/s)
N: 100 (m) 600 (m/s)
O: 50 (m) 600 (m/s)
The wave with the lowest frequency is wave O, as it has the largest wavelength and is inversely proportional to frequency.
A student moves the end of a compressed coiled spring up and down to demonstrate wave motion. She then moves the compressed coiled spring faster but keeps everything else the same. Which characteristics will increase?
Crest
Frequency
Amplitude
Wavelength
If the student moves the compressed coiled spring faster while keeping everything else the same, the characteristics that will increase are:
Frequency: The frequency of the wave will increase, as it is determined by the number of complete oscillations or cycles that occur per unit of time. Moving the spring faster will result in more cycles happening within the same amount of time, thus increasing the frequency.
Crest: The crest of the wave will not be affected by the speed at which the spring is moved. The crest refers to the highest point of the wave, and it does not change based on the speed at which the wave is generated.
Amplitude: The amplitude of the wave will not be affected by the speed at which the spring is moved. The amplitude refers to the maximum displacement or distance from the equilibrium position that any point on the wave achieves. It is not determined by the speed at which the wave is generated.
Wavelength: The wavelength of the wave will not be affected by the speed at which the spring is moved. The wavelength refers to the distance between two corresponding points on a wave, such as two crests or two troughs. It is not determined by the speed at which the wave is generated.
