Here is a question bank on 7th grade waves unit of Physical Science containing 24 questions on all types of waves. It includes sound, electromagnetic, etc.
It covers the following objectives in details:
2. Develop an understanding of chemical and physical changes, interactions involving energy, and forces that affect motion of objects.
e. Distinguish how various types of longitudinal and transverse waves (e.g., water, light, sound, seismic) transfer energy. (DOK 2) Frequency Wavelength Speed Amplitude
It also prefaces the electromagnetic spectrum for future understanding! It'll make their knowledge of the Spectrum much more enhanced for their grade than others I've found!
