- 1How to sound waves move through the air?Air has particles that are moving in random directions, whenever something emits a sound it vibrates. These vibrations cause the air around it to vibrate too. The vibrating particles move around so they bump into one another transmitting the sound from one place to another.
- 2What is sound?Vibration transmitting sound
- 3What determines the wavelength?The pitch
- 4Another word for wavelength?Frequency
- 5The higher the frequency...?The shorter the wavelength
- 6What is amplitude?The amplitude is measured from the top of the wave to the equilibrium or the straight line going through the center of the wave.
- 7What determines the amplitude?How loud the noise is
- 8Turnover for a diagram.
- 9What are the different parts of the wave?1. The top part of each wave is called the crest while the lowest is called the trough. 2. The distance from crest to crest is the wave length and the amplitude is measured from the center line (equilibrium position) to the crest.

- 11Speed of sound340 mps (metres per second)
- 12Speed of light300 millions
- 13What does the electromagnetic spectrum consist of?1. Gamma Rays
2. X-rays
3. Ultraviolet
4. Visible light
5. infrared
6. Microwave
7. Radio - 14Diagram
- 15What is Total internal reflection(TIR)?When prisms are used for reflections instead of mirrors, light can bounce off of the inner surface rather than just the outer. This means that the angle of the reflected light can be more easily adjusted.
