## Introduction to Nuclear Physics and Optics

Semester 2

This is a pre-calculus course covering fundamental topics in Nuclear Physics and Optics.

Syllabus:

Optics ( 11 Lectures):

• Light as Electromagnetic Wave:
• The electromagnetic spectrum.
• The speed of light.
• Wavefronts and rays.
• Laws of reflection.
• Image formation by Concave and convex mirrors.
• Refraction of light.
• Index of refraction.
• Snell’s law.
• Total internal reflection and the critical angle. Examples of application of TIR.
• Lenses:
• Thin converging and diverging lenses.
• Image formation by lenses using ray diagrams.
• Linear magnification.
• Derivation of the lens equation and sign convention.
• Lenses in combination.
• Human Eye:
• Anatomy of the human eye.
• Image formation by the eye of objects at varying distances.
• Defects of vision (nearsightedness and farsightedness) and their correction by lenses.
• Telescopes and Microscopes:
• Angular magnification.
• Simple and compound microscopes their angular magnification.
• Astronomical and Galilean telescopes and angular magnification.

Nuclear Physics ( 7 Lectures)

• Nuclear Model of the Atom:
• Geiger-Marsden experiment.
• Nuclear structure.
• The fundamental forces.
• Binding energy and mass defect.
• Atomic mass unit.
• Nuclear stability and natural radioactivity.
• Fission and fusion.
• Radioactive decay and its equation.
• Medical and other applications of radioactivity.
• X-ray production and spectrum.
Evaluation:

One 2-hour theory examination paper                                                60%

Two 1-hour in-course tests (15% each)                                               30%

Laboratory work (average of 6 labs at 10% each)                              10%

Learning Objectives:

After completing this course, students should be able to:

•  Appreciate that no material body, in free space, can travel faster than the speed of light.
• Perform quantitative analyses of problems of image formation with concave and convex mirrors and thin lenses.
• Explain the defects of vision and the methods of correction using appropriate lenses. In addition, to perform the necessary quantitative analysis to determine the focal length of the corrective lens.
• Explain the construction of the compound microscope and the astronomical telescope and calculate the angular magnification in each case.
• Explain the structure of the nucleus.
• Explain the concepts of “binding energy” and “mass defect” and perform simple calculations to determine these quantities.
• Explain nuclear stability and radioactive decay.
• Perform and interpret the results of simple experiments and demonstrations of physical principles.
