Part II

1. Course Aims: Vibrations, mechanical waves, light waves, and ray optics are commonly found and used in daily life. As fundamental topics in physics, waves and optics are important for more advanced courses in applied optics program. This course aims to lay down the foundation knowledge in waves and optics and its applications in such a way that the students can identify the appropriate concepts required in given physics problems and apply them to formulate suitable physics solutions.

AP3204 (3-3-4) 1 2. Course Intended Learning Outcomes (CILOs) (state what the student is expected to be able to do at the end of the course according to a given standard of performance)

Upon successful completion of this course, students should be able to:

No CILOs Level of Importance 1 Identify and describe the vibration and wave natures of 2 representative systems in daily life. 2 Identify the wave properties in optics. 1 3 Apply the basic concepts and theories on the wave 3 formations and propagations in media to explain and predict phenomena in daily life. 4 Apply basic superposition theory to solve simple 3 problems in interference and diffraction. 5 Recognize the disasters caused due to the improper use 1 of vibrations and waves.

3. Teaching and Learning Activities (TLAs) (designed to facilitate students’ achievement of the CILOs)

AP3204 (3-3-4) 2 5. Grading of Student Achievement: Refer to Grading of Courses in the Academic Regulations (Attachment) and to the Explanatory Notes.

The grading is assigned based on students’ performance in assessment tasks/activities.

Grade A The student completes all assessment tasks/activities and the work demonstrates excellent understanding of the scientific principles and the working mechanisms. He/she can thoroughly identify and explain how the principles are applied to science and technology for solving physics and engineering problems. The student’s work shows strong evidence of original thinking, supported by a variety of properly documented information sources other than taught materials. He/she is able to communicate ideas effectively and persuasively via written texts and/or oral presentation.

Grade B The student completes all assessment tasks/activities and can describe and explain the scientific principles. He/she provides a detailed evaluation of how the principles are applied to science and technology for solving physics and engineering problems. He/she demonstrates an ability to integrate taught concepts, analytical techniques and applications via clear oral and/or written communication.

Grade C The student completes all assessment tasks/activities and can describe and explain some scientific principles. He/she provides simple but accurate evaluations of how the principles are applied to science and technology for solving physics and engineering problems. He/she can communicate ideas clearly in written texts and/or in oral presentations.

Grade D The student completes all assessment tasks/activities but can only briefly describe some scientific principles. Only some of the analysis is appropriate to show how the principles are applied to science and technology for solving physics and engineering problems. He/she can communicate simple ideas in writing and/or orally.

Grade F The student fails to complete all assessment tasks/activities and/or cannot accurately describe and explain the scientific principles. He/she fails to identify and explain how the principles are applied to science and technology for solving physics and engineering problems objectively or systematically. He/she is weak in communicating ideas and/or the student’s work shows evidence of plagiarism.
