This module is designed to introduce students to the fundamentals of Physics in the areas of Geometrical Optics, Properties of Waves, Sound and Physical Optics. The learning of the student will be enhanced in the lecture programme through the introduction of appropriate examples and applications relevant to the field of study of the students. A laboratory element is included to support the theoretical material and to develop the laboratory skills of the student.
The aim of this module is to provide the student with a basis in Physics in the areas specified, to enable them to work with standard physical laws and measurements. On successful completion of it the learner should be able to explain relevant terminology and associated concepts, perform calculations, solve problems, apply concepts to new problems. They should be able to plan and perform experiments, collect data, analyse data and present results.
