Study Notes

Module Overview

Focuses on Waves: Sound and Light in Medical Physics.
Activities include mini-lab, group discussions, video reviews, and laboratory experiments.
Four main topics: Waves, Sounds, Electromagnetic Waves, and Lights.

Learning Outcomes

Develop critical thinking and qualitative analysis in physics.
Apply mathematical techniques for quantitative problem-solving in physics.
Communicate technical knowledge clearly and utilize computer tools for data analysis and report preparation.

Course Structure

Total duration: 48 hours, divided equally among four topics (12 hours each).
Topics include:
- Waves
- Sound
- Electromagnetic Waves
- Light
Online delivery through Google Classroom, available in synchronous or asynchronous formats.

Waves

Topics cover wave descriptions, properties, behavior, and calculations (speed, wavelength, frequency).
Waves consist of high points (crests) and low points (troughs).

Compressional Waves

Mechanical waves can be transverse or compressional.
In compressional waves, the medium's particles move forward and backward in the same direction as the wave.
Example: Compressional wave created by squeezing coils in a spring.

Sound Waves

Sound waves are compressional waves formed by vibrating objects.
Human voice produces sound through vocal cord vibrations.
Observing vibrations can be done by feeling a stereo speaker or drumhead.

Light Waves

Light waves are produced by sources like the Sun or lightbulbs and reflect off surfaces.
Smooth surfaces yield clear reflections; rough surfaces scatter light, resulting in unclear images.

Refraction and Diffraction

Refraction occurs when waves change direction while passing through different mediums.
Activity to observe light refraction with a straw in water illustrates changes in appearance caused by light bending.
Light waves refract at different angles based on wavelength, separating into visible spectrum colors.

Diffraction

Light waves do not diffract as significantly as sound waves due to smaller wavelengths.
Light wavelengths: 400 to 700 billionths of a meter; sound wavelengths range from a few millimeters to about 10 meters.
Similarity in size between wavelengths and barriers increases diffraction effects.
