9-11 PS3D
Waves (including sound, seismic, light, and water waves)
transfer energy when they interact with matter. Waves
can have different wavelengths, frequencies, and
amplitudes, and travel at different speeds.
9-11 PS3E
Electromagnetic waves differ from physical waves
because they do not require a medium and they all travel
at the same speed in a vacuum. This is the maximum
speed that any object or wave can travel. Forms of
electromagnetic waves include X-rays, ultraviolet, visible
light, infrared, and radio.
Waves and Optics
Stage 1 – Desired Results
Transfer
Students will be able to independently use their learning to …
 Understand the properties of waves, how waves transfer energy and how this energy is transferred
or changed within a system.
 Understand how the properties of electromagnetic waves leads to the development of medical
technologies
Meaning
Understandings (Non-negotiable)
Students will understand that …
 Energy can be transmitted by sending waves
through a medium.
 Physical waves can be described by their
characteristics of frequency, wavelength,
amplitude, and speed.

The properties of waves lead to the pitch
and volume of sound waves and to the
wavelength and magnitude of water waves.
Regions of the electromagnetic spectrum
differ regarding wavelength, frequency, and
energy, and the technology can be applied in
different ways (e.g., infrared in heat lamps,
microwaves for heating foods, X-rays for
medical imaging).
Recommended Essential Questions
Students will keep considering …
 How does a wave transfer energy?
 What is the relationship between
wavelength and frequency?
 How do waves create the sounds that I hear
and the colors that I see?
 How can waves interfere with each other?
 Why does the police siren sound different
when it passes by me?
 What is light?
 Why do objects appear to be different
colors?
 How can we explain the colors in a rainbow?
 How do microscopes and telescopes work?

determine the amplitude, wavelength and frequency of a wave from
such a graph.
• Describing how waves respond at boundaries between media in
terms of reflection, refraction and diffraction.
