Relate frequency and wavelength
Relate frequency and wavelength using supplied evidence and a solved model.
About 25 minutes, plus any extended practice
Open lesson 1Wave Optics and Resolution
Calculate wave and ray quantities and distinguish model assumptions.
Before you begin
- Read or listen to supplied scientific descriptions and follow a labeled diagram.
- Use signed quantities, ratios, exponents and the explicitly supplied model formulas.
Choose by skill rather than age alone. Read with an adult when useful, revisit a lesson, or explore another grade.
