Online CEGEP Waves & Optics Tutoring
Connect oscillations, wave superposition and optical models in CEGEP physics. Waves courses in Science programs may also include modern physics; send your chapter so we can confirm tutoring availability.
Start with a concept you would like explained or a question you do not yet know how to begin. A course outline or an attempted solution can help if you have one. We confirm the level, topics and availability before booking. Tutoring sessions are currently offered in English. In-person options in Montréal
Choose the wave or optics question you want to understand
Choose an explanation or practice question below. For other oscillations or optics topics, tell us your topic; a course outline can help us confirm the scope.
- Graphs or motion? Start with the worked wave-speed example, then compare a crest with a particle in the full lesson.
- A slit pattern? Compare diffraction width and interference spacing using the aperture diagram.
- An oscillator starts between its turning points? Use its initial position and signed velocity to choose the phase and find the first equilibrium crossing.

- Choosing ray optics or wave optics for the physical scale
How tutoring can help
Tell us which idea feels unclear, or bring a graph, equation or diagram you are working on. We can start with the basic concepts. A tutor can help you label the axes, distinguish a particle’s motion from the wave’s propagation, and connect the quantities before calculating. You can then try a similar question together. We confirm your course topics and availability before booking.
Ask about waves tutoringCurrent and former course codes
This table matches current and former codes by Science program subject. Your institution must confirm any transfer-credit equivalence. The prefix matters: 201-SN1 is probability and statistics, while 203-SN1 is mechanics. Course codes and topics can vary by institution. Check your current course outline.
| Subject | Current code | Former code |
|---|---|---|
| Waves and modern physics | 203-SN3-RE | 203-NYC-05 |

Distinguish wave speed from particle motion
An ideal transverse wave travels right along a string. Its wavelength, the distance between neighbouring crests, is . Each particle completes an up-and-down oscillation in one period, . How fast does the wave profile travel?
In one period the profile advances by one wavelength, so its propagation speed is . Here describes the moving profile. Each tagged part of the string keeps its horizontal position and oscillates vertically in this ideal model. A crest moves from one particle to another; it is not a particle carried along the string.
Read the full guide: a wave in space and time
Compare the two graphs, follow a crest and a particle, and try three questions with explained answers.
Compare diffraction width and interference spacing
Working on slit patterns? Start with one aperture diagram and one distance at a time.
What to practise
Alternate wave graphs, standing-wave patterns and numerical interference questions. State the boundary conditions rather than selecting a harmonic formula by appearance. Use your outline to confirm which optics, quantum or nuclear topics are included; the course title alone is insufficient.
