1.2 Wavelength or frequency?

In this unit you will find frequent references both to the wavelength of light and the frequency of light. It is important to be able to work with both, and convert from one to the other. In the context of optical-fibre communication, the light radiation we are concerned with is usually in the infrared region of the spectrum.

To identify the position in the electromagnetic spectrum it is usual to refer to the wavelength of light, rather than its frequency. Thus I will refer to the ‘13

4.2.1 Defining the problem

It is vital that the problem is identified correctly. If the risk management system is working properly, the problem should not have hit you completely out of the blue, and you should already have some idea what it is about. But, although there is often a temptation to skip the definition phase and go straight to causes and solutions, it is important to be as clear as possible about the nature of the problem as seen from different perspectives, by answering questions such as those below.

In this manner, "Design in Freedom" is both a premise and a slogan. It is a multidisciplinary approach from the conceptual basis of design freedom and the tools that provides us. In the current context of the knowledge society, design, development and its cognition must be

After leaving the area as a child the Romantic poet William Wordsworth returned to the Lake District and remained there from 1799 to 1802. Surrounded by scenery he cherished Wordsworth composed some of his best poetry in Dove Cottage, but the building was also the residence of friend Thomas De Quincy whom documented his time with the Wordsworth’s as well as his own experiences in the property.
