Activities

PS-7.1    Illustrate ways that the energy of waves is transferred by interaction with matter (including transverse and longitudinal/compressional waves).

PS-7.2    Compare the nature and properties of transverse and longitudinal/compressional mechanical waves.

PS-7.3    Summarize characteristics of waves (including displacement, frequency, period, amplitude, wavelength, and velocity as well as the relationships among these characteristics).

PS-7.4    Use the formulas v = f and v = d/t to solve problems related to the velocity of waves.

PS-7.5    Summarize the characteristics of the electromagnetic spectrum (including range of wavelengths, frequency, energy, and propagation without a medium).

PS-7.6    Summarize reflection and interference of both sound and light waves and the refraction and diffraction of light waves.

PS-7.7    Explain the Doppler effect conceptually in terms of the frequency of the waves and the pitch of the sound.
