Module Title:Principles of Light and Sound
Language of Instruction:English
Credits: 10
NFQ Level:6
Module Delivered In 2 programme(s)
Teaching & Learning Strategies: A combination of lectures, laboratory practicals, demonstrations and projects will be used. Particular emphasis will be placed on active learning especially problem/project based learning and team work. In parallel with the lecture programme, each student will be asked to complete a range of practical assignments. Lectures: A series of lectures, using whiteboard, data projector and video, will initiate and broaden the students’ knowledge of the scientific principles. Practicals: A series of demonstrations and practical exercises designed to motivate the students and develop their learning of scientific principles. The practical sessions will focus the students on the concepts in order to enhance their understanding and develop their analytical skills.
Module Aim: The aim of this course is to give students an understanding of: the characteristics of sound and light; how light and sound is captured, stored, processed and transmitted electronically; human physiology in relation to sight and hearing.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Understand the fundamentals of measurement science
LO2 Describe the properties of light and sound
LO3 Explain the technical aspects of how light/sound is captured, stored, processed and transmitted
LO4 Demonstrate and apply the technical skills and knowledge required to measure specific properties of light and sound, e.g. wavelength, frequency
LO5 Apply the knowledge of light and sound to TV/Media applications, working autonomously and as a member of a team on selected applied projects
LO6 Identify and recommend appropriate approaches solutions to applied problems
