Wave Speed, Frequency, and Wavelength Practice Set
A 10-problem practice worksheet for 9th grade science that builds fluency with the wave speed equation v = fλ, including unit conversions and rearranging the formula to solve for frequency or wavelength. It opens with a reference section covering the formula, variable key, and a formula triangle, making it a solid independent practice or homework set after introducing wave basics.
Teacher Guide & Tips
- Use this as guided practice after a mini-lesson on the wave equation, or assign it as homework once students have seen one or two worked examples in class.
- Discussion question: If the frequency of a wave doubles while its speed stays the same, what happens to its wavelength, and why?
- Scaffold for struggling readers: have students first circle the given quantities and write the units for each before choosing a formula, and provide the formula triangle as a visual reminder of how to rearrange v = fλ.
- Extension for advanced students: ask them to compare wave speeds in two different media, such as sound in air versus water, and explain what the data suggests about the medium's role.
- Plan roughly 30 to 40 minutes for the full set, depending on how many problems require unit conversions.
