Creating Waves: Understanding Amplitude, Frequency, Period, and Velocity

What happens to the amplitude, frequency, period, and velocity of a wave when you shake your hand back and forth faster without changing the distance your hand moves? Amplitude - remains the same
Frequency - increases
Period - decreases
Velocity - remains the same.

Understanding the Effects of Shaking Your Hand Faster on Waves

When you create waves by shaking your hand back and forth, there are key aspects of the wave that are affected when you increase the speed of your hand movements. Let's break down the changes in amplitude, frequency, period, and velocity:

Amplitude:

The amplitude of a wave is the maximum height of the wave. In this scenario, as you shake your hand faster while keeping the distance constant, the amplitude of the wave will remain the same. This is because the amplitude is determined by the distance your hand covers while moving, which has not changed in this situation.

Frequency:

The frequency of a wave refers to how many complete cycles of the wave occur in a given time period. By shaking your hand faster, you are increasing the number of times your hand moves back and forth in the same amount of time. As a result, the frequency of the wave will increase because there are more cycles happening in a set period.

Period:

The period of a wave is the time it takes for one complete cycle to occur. When you shake your hand faster, the wave will travel more quickly as well. This means that the time needed for the wave to complete one cycle, or its period, will decrease. The wave will cover the same distance in less time due to the increased speed of your hand movements.

Velocity:

The velocity of a wave depends on the medium through which it is traveling. In this case, since the wave is being created by your hand movements in the air and the medium remains constant, the velocity of the wave will remain unchanged. The speed at which the wave travels through the air will stay the same despite the increase in frequency and decrease in period caused by shaking your hand faster.

By understanding how changing the speed of your hand movements affects the amplitude, frequency, period, and velocity of a wave, you can grasp the dynamic nature of wave behavior and how these fundamental properties interact with each other.
