Science/Making waves

This week we have been learning about transverse waves and they work. We tested our hearing by listening to a video who made a noise that went louder and louder to see how good our hearing is. We also used this equipment which is called tuning fork. We banged the table with the tuning fork and put the equipment next to our ear and see if we could hear anything.

Aim: To test my hearing

Materials/Equipment
Tuning fork
Steps
Get a tuning fork
Bang it on anything that is metal
Test your hearing
Method:
  1. Listen to the sound test YouTube/device
  2. Record what my hearing level is
My findings:
Better than advrage

A.Crest

B.Wave

C.Amplitude

D.Trough

Longitudinal
Loudest

Waves, transfer energy from one to another

Wave motions:.
Waves are produced as a result of vibrations, and can be classified
as transverse or longitudinal. Whether they are transverse or Longitudinal, depends upon how the particles are made to vibrate, as the energy passes.

Example of Longitudinal waves Sound:

When a drum is struck, the drums can vibrate, which causes the air particles next to it, to vibrate.
The vibrating air speeds away from the source, creating a sound wave.

Research:
In a transverse wave, the particles of the medium move perpendicular to the wave's direction of travel. Transverse waves are characterised by peaks and valleys, called crests and troughs. In a longitudinal wave, the particles of the medium move parallel to the wave's direction of travel.

To support my learning I ask you to comment as follows:
1. Something positive - something you like about what I have shared.
2. Thoughtful - A sentence to let us know you actually read/watched or listened to what I had to say
3. Something thoughtful - how have you connected with my learning? Give me some ideas for next time or ask me a question.
