Light & Sound

4 interactive Integrated Science simulations on light & sound.

Integrated Science · Light & Sound Pitch and loudness of sound – comparing two sounds on an oscilloscope A tuning fork or a string vibrates with a frequency f and amplitude A chosen by the student; an oscilloscope shows the waveform, and... Ages 12–13
Integrated Science · Light & Sound Refraction, total internal reflection and lenses Top half: a light ray travels from medium n₁ into medium n₂ — drag the light source to change the angle of incidence and watch the angle... Ages 14–15
Integrated Science · Light & Sound Reflection on a Plane Mirror, Virtual Image, Umbra and Penumbra Reflection mode: drag light source S to change the angle of incidence; the reflected ray, the normal, and both angles i and i′ are drawn... Ages 12–13
Integrated Science · Light & Sound Sound waves – frequency (pitch) and amplitude (loudness) A speaker membrane vibrates, causing air particles in a tube to bunch together and spread apart; these compression and rarefaction... Ages 12–13
