When a pulse travels along a medium and reaches a fixed end, it is reflected back towards the original direction. However, the medium at the fixed end cannot move, so the reflected pulse is inverted or upside down. This is because the particles of the medium at the fixed end are forced to move in the opposite direction of the incoming pulse, causing the reflected pulse to be inverted.
The amplitude of the reflected pulse is equal to the amplitude of the incident pulse. This means that the height of the reflected pulse will be the same as the height of the incident pulse. However, the direction of the pulse will be inverted, as mentioned in the previous question.
No, the speed of the pulse does not change after it reflects off of a fixed end. The speed of a wave depends on the properties of the medium it is traveling through, and the medium at the fixed end does not change. Therefore, the speed of the pulse remains the same.
The wavelength of the pulse remains the same after it reflects off of a fixed end. This is because the medium does not change, and the wavelength is determined by the properties of the medium. The only change that occurs is the direction of the pulse, as it is inverted.
Yes, a pulse can be reflected multiple times off of a fixed end. Each time the pulse reflects, it will be inverted and travel in the opposite direction. This process can continue until the pulse loses enough energy and dissipates, or until the fixed end is no longer present.
