A pulse of the shape below originates in spring A. The speed of the pulse in this spring is 4.0 m/s. Another spring, B, is connected to spring A. The speed of the pulse in spring B is 2.0 m/s. The “short” end of the original pulse is the right side with the steep decline.
1) Draw a diagram showing the reflected pulse. In your diagram, pay particular attention to the wavelength of the reflected pulse, the amplitude of the pulse, whether or not it is inverted, and in what direction the “short” end of the pulse is facing.
2) Draw a diagram showing the partially transmitted pulse. In your diagram, pay particular attention to the wavelength of the transmitted pulse, the amplitude of the pulse, and in what direction the “short” end of the pulse is facing.
3)Of the quantities, speed, wavelength, frequency, and amplitude, which of these does not change as a wave is partially reflected or partially transmitted?
4)Of the quantities, speed, wavelength, frequency, and amplitude, which of these is always decreased in size as a wave is partially reflected or partially transmitted?
