# Draw Two Sound Waves To Illustrate Different Frequencies And Amplitudes

Sound waves are a type of energy that can be heard by the human ear. They are created when an object vibrates and causes the air particles around it to vibrate as well. The resulting waves move through the air and can be detected by our ears.

## What are Frequencies and Amplitudes?

Sound waves have two important properties: frequency and amplitude. Frequency is the number of waves that pass a given point in a second, and is measured in Hertz (Hz). Amplitude is the height of the wave, and determines how loud the sound is.

Frequency and amplitude are related, but they are not the same thing. A high frequency sound wave will have more waves passing a given point in a second, but it may not be very loud if the amplitude is low. Similarly, a low frequency wave may have fewer waves passing a given point, but it can still be loud if the amplitude is high.

## Examples of Sound Waves with Different Frequencies and Amplitudes

Here is an example of a sound wave with a high frequency. As you can see, there are many waves passing a given point in a second. This sound could be a high-pitched whistle or a bird chirping. However, the amplitude of this wave is low, so it may not be very loud.

Here is an example of a sound wave with a high amplitude. As you can see, the wave is much taller than the previous one. This sound could be a loud explosion or a bass-heavy piece of music. However, the frequency of this wave is low, so there are fewer waves passing a given point in a second.

## How to Draw Sound Waves

Now that we know what frequency and amplitude are, let’s learn how to draw sound waves. To draw a sound wave, you will need a piece of paper and a pen or pencil.

Start by drawing a straight line across the paper. This line represents the baseline of the sound wave. Next, draw a wave-shaped line above the baseline. The height of the wave represents the amplitude, and the distance between the peaks represents the frequency.

You can adjust the frequency and amplitude of your wave by changing the distance between the peaks and the height of the wave. Experiment with different shapes and sizes until you find a wave that you like.

## Conclusion

Sound waves are an important part of our daily lives, and understanding how they work can help us appreciate the sounds around us. By drawing sound waves with different frequencies and amplitudes, we can see how these properties affect the way we hear sound.
