Sound and Pitch Interactive Simulation
អំពីការពិសោធន៍និម្មិតនេះ
Sound travels through air at about 343 m/s. The pitch you hear depends on frequency (f): a higher note vibrates faster, packing more wave cycles into a second, which shortens the wavelength (λ = v / f). A concert A (440 Hz) has a wavelength of about 78 cm. Students can change frequency and compare what happens. Use it for physics inquiry with Grades 4–5, Middle School, and High School on a projector or student device.
ស្តង់ដារ៖ NGSS 4-PS4-1
អ្វីដែលសិស្សអាចស្វែងរកបាន
- How raising the frequency (higher pitch) squeezes the wave and shortens λ
- Why bass notes (low f) have very long wavelengths while dog whistles are tiny
- Reading λ = v/f off the live formula as you slide the frequency
គោលបំណងសិក្សា
- 1Predict how changing frequency will affect the wavelength, then test the prediction.
- 2Use evidence from the live calculation and visual to explain the result.
