D860: General Physics II with Lab

General Physics II with Lab builds on the fundamentals with thermodynamics, optics, and atomic/nuclear physics — a genuinely broad survey of advanced physics content.

What D860 covers

The course builds on foundational concepts from General Physics I, guiding students through heat and thermodynamics, geometric optics, and interactions/transformations of energy within atomic and subatomic systems. Students explore heat vs. temperature, heat transfer methods, specific heat capacity, thermodynamics laws, and heat engines.

The course delves into electromagnetic waves, Snell's law, total internal reflection, thin film interference, ray tracing, dispersion, polarization, and diffraction, then analyzes atomic models, spectral absorption/emission, radioactivity, and nuclear processes like fusion and fission.

The D860 performance assessment

Expect a performance assessment requiring you to apply a thermodynamics, optics, or nuclear physics principle to explain a specific physical phenomenon.

Key topics in D860

• Thermodynamics and heat transfer
• Geometric optics
• Atomic structure and spectral analysis
• Radioactivity and nuclear processes

Writing tips for D860

Follow the task instructions and rubric line by line

WGU performance assessments for D860 are graded against a fixed rubric — every rubric line has to be visibly addressed, usually with a labeled heading that mirrors the rubric language. Skipping a rubric point because it seems minor is the single most common reason a competent submission comes back "Not Yet Competent" for revision.

Connect content mastery to the classroom you'll eventually teach

Even content-heavy science courses like D860 in a Science Education degree ultimately serve teaching goals. Where the task allows, connecting content mastery to how you'd explain it to secondary students strengthens a response beyond content accuracy alone.

Because WGU is self-paced, don't let "no deadline pressure" become no submission

There's no weekly due date forcing progress, which means procrastination costs more at WGU than at a traditional term-based school — a stalled task can quietly eat weeks of a term. Treat your own target date for each D860 assessment as a real deadline.

Why students seek help with D860

Candidates sometimes address only one topic area (say, only optics) when the course spans thermodynamics, optics, AND nuclear physics — a strong response demonstrates command across the assigned topic area with appropriate depth.
