Module Title:Principles of Light
Language of Instruction:English
Credits: 5
NFQ Level:6
Module Delivered In No Programmes
Teaching & Learning Strategies: A mixture of active learning and prescribed learning will be implemented. Prescribed learning will take the form of lectures where the student will be introduced to core concepts in light and other forms of electromagnetic radiation to allow the student to develop their unistructural and multistructural knowledge in a controlled learning environment. Active learning will take the form of laboratory exercises where students will examine fundamental properties of light such as reflection, refraction, and inverse square path loss behaviour along with lens parameters and polarization filters. The goal of these active learning sessions in the laboratory will be to facilitate the student to be able to relate the prescribed knowledge of the lectures with real-life objects such as lenses and filters. Written assignments will be used to strengthen the understanding of both the prescriptive and active learning aspects of the module.
Module Aim: The aim of this module is to allow the student the opportunity to understand difficult but fundamental ideas from Physics with an emphasis on their practical ramifications. It is furthermore envisioned that the knowledge developed here can later be extended as it will compliment later modules, which they will undertake in their degree, that focus on camera-operation, filming & lighting.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Describe the properties of light itself & objects that interact with or manipulate light.
LO2 Comprehend & measure light & the parameters of objects that interact with or manipulate light.
LO3 Relate the properties & measurements of light & associated objects with the principles of the technologies that capture, store, process and transmit light.
LO4 Demonstrate competency in the ability to measure and characterise properties of light such as wavelength, polarization & brightness.
LO5 Judge & appraise important parameters such as focal length, aperture, shutter speed, ISO and polarization with a view to applying these practically in photography & filmmaking.
LO6 Evaluate light-colour reproduction standards with a view to assessing image and film quality.
LO7 Develop problem-solving skills broad enough to be applied in an industry where the use of technology changes rapidly.
