What we will do today

In this experiment, we will explore the properties of sound waves. We will learn that sound is produced by vibrating objects and transfers energy as a wave. We will also investigate how sound travels through different mediums and explore if it can travel through a vacuum.

Presentation Transcript

  1. What we will do today • Carry out experiments on sound waves. • State that for sound to be produced an object must vibrate. • State that sound is a wave which transfers energy. • State that the frequency of a sound is the number of waves produced in a second and is measured in a unit called Hertz. • State how sound travels. • Investigate if sound can travel through solids, liquids and gases. • State what is meant by a vacuum. • Investigate if sound can travel through a vacuum.

  2. Sound Waves • For sound to be produced an object must vibrate. • Sound is a wave which transfers energy. • The frequency of a sound is the number of waves it produces in one second. • Frequency is measured in Hertz (Hz).

  3. Sound Travels • Today we are going to investigate how sound travels. • What apparatus could you use to find out whether or not sound travels through solids, liquids and gases?

  4. Sound Travels • Copy and complete the following table.

  5. Sound Travels • Sound can travel through solids, liquids and gases. • Sound cannot travel through a vacuum.
