Supplementary Physics 3

Course Title: Supplementary Physics 3

Subject Code: SC 32203

Grade Level: Grade 11

Course Overview:

Supplementary Physics 3 provides Grade 11 students with a comprehensive exploration of wave mechanics and optical phenomena. Building upon foundational physics principles, this course examines the mathematical and physical concepts governing how mechanical, sound, and light energy propagate through various media. Students will analyze fundamental wave properties, boundary behaviors, superposition, and wave-particle interactions through visual models, problem-solving, and practical applications.

Key Topics Covered:

• Mechanical Waves: Wave types, pulse behavior, amplitude, wavelength, frequency, and wave speed calculations.

• Wave Boundary Behavior: Reflection, transmission, refraction, phase inversion, and energy transfer across medium boundaries.

• Interference & Diffraction: The principle of superposition, constructive and destructive interference, standing waves, nodes/antinodes, and Huygens’ principle.

• Light Waves: The electromagnetic spectrum, polarization, dual nature of light, and wave propagation characteristics.

• Light Optics: Geometric and physical optics, including reflection, refraction (Snell’s Law), total internal reflection, thin lenses, mirrors, and diffraction gratings.

• Sound Waves: Acoustic properties, speed of sound in media, intensity levels, pitch, resonance, beat frequencies, and the Doppler effect.

Learning Outcomes:

By the end of this course, students will be able to predict and mathematically evaluate wave interactions, model optical phenomena using ray diagrams, and apply wave behavior models to real-world technological and natural applications.
