5.11 Vibrating air column: standing waves in a conical tube
How do different instruments produce the sounds we classify as music? How do we decide whether something – a piano, a vacuum cleaner – is actually a musical instrument? In this unit we investigate the way vibrations and sound waves are harnessed to create music.

How do different instruments produce the sounds we classify as music? How do we decide whether something – a piano, a vacuum cleaner – is actually a musical instrument? In this unit we investigate the way vibrations and sound waves are harnessed to create music.
5.9 Vibrating air column: standing waves in a cylindrical tube closed at one end
How do different instruments produce the sounds we classify as music? How do we decide whether something – a piano, a vacuum cleaner – is actually a musical instrument? In this unit we investigate the way vibrations and sound waves are harnessed to create music.
5.8 Vibrating air column: standing waves in a cylindrical tube open at both ends
How do different instruments produce the sounds we classify as music? How do we decide whether something – a piano, a vacuum cleaner – is actually a musical instrument? In this unit we investigate the way vibrations and sound waves are harnessed to create music.
5.7 Vibrating air column: reflection at the end of an air column
How do different instruments produce the sounds we classify as music? How do we decide whether something – a piano, a vacuum cleaner – is actually a musical instrument? In this unit we investigate the way vibrations and sound waves are harnessed to create music.
5.4 Vibrating string: normal modes of vibration
How do different instruments produce the sounds we classify as music? How do we decide whether something – a piano, a vacuum cleaner – is actually a musical instrument? In this unit we investigate the way vibrations and sound waves are harnessed to create music.
11.1 What are they?
Computer crashes are often the result of viruses, worms or Trojans as unfortunately some internet users want to cause havoc or vandalise your computer. This unit provides a guide to the downsides of living with the Net. Advice on how to deal with these dangers is provided and security issues like spyware and adware are explained. The unit also deals with protecting children online, and provides links to various helpful websites which deal with the problems raised.

Ned's fortunes seem to rely on control of the IPR issues surrounding his invention. He challenges the rights of others to share in the IP because, as he sees it, they have not contributed anything. The assumption is that those that have the idea have IPR, but the IPR has value and, therefore, any proceeds accrued should be due to the person who has the idea. A problem arises here because of the phrase ‘in 5.3 Ethics and ethos: ‘does mum know?’ In Act 1 we are presented with a fairly naïve Ned, who initially believes himself to be in control. We discover he is very proud of his intellectual achievements and less concerned with money. He explains his inventions and, when he does so, he finds analogies that highlight the aesthetics of what he is designing. At a crucial point in the conversation, his brother Dan asks: ‘does mum know?’ This is a really significant point in the play because it draws in another relationship

Looking at the bigger picture of Africa’s improving economic fortunes in the past decade, it is clear that China’s influence in Africa has been largely a success story.
Two reasons why shrimp are considered to be crustaceans is because they have two pairs of antennae and jointed legs.
Student teams investigate the properties of electromagnets. They create their own small electromagnet and experiment with ways to change its strength to pick up more paper clips. Students learn about ways that engineers use electromagnets in everyday applications.
Even as the space shuttle program comes to a close, NASA is already building its next human spacecraft, the Orion Multi-Purpose Crew Vehicle (MPCV), around the country. Orion is being designed and tested to go further than we've ever gone and do things the shuttle could never do, namely explore deep space. In "Orion: The Journey Begins" take a look at the progress and development of NASA's newest vehicle, which will be the most advanced human spacecraft ever built.
