(SECONDARY)
ESSENTIAL UNIT (E09)
(Waves, Electromagnetic Spectrum, and Optics)
(June 2011)
Unit Statement: The student will investigate waves, their parts, and their interactions. The
properties of light, how it is produced, and the order of waves in the electromagnetic
spectrum are described in this unit. The manipulation of light by mirrors and lenses and
optical instruments are also presented.
Essential Outcomes: (Must be Assessed)
1. The Student Will describe the different types of waves (transverse, longitudinal, and
surface) and how they are produced and analyze the motion of a medium as each kind of
wave passes through it. (p. 500 – 503)
2. TSW define frequency, wavelength, period, and wave speed and solve equations
relating wave speed to wavelength and frequency or period. (p. 504 – 506)
3. TSW describe how to measure amplitude and relate amplitude to the energy of a
wave. (p. 507)
4. TSW differentiate between reflection, refraction, diffraction, and the two types of
interference of waves, identify the factors that affect the amount of each, and
describe how they affect waves. (p. 508 – 512)
5. TSW describe the characteristics of electromagnetic waves and calculate the
wavelength and frequency of an electromagnetic wave given its speed. (p.
533 – 536)
6. TSW explain the nature of light as both particle and wave and describe the
evidence for the dual nature of electromagnetic radiation. (p. 536 – 537)
7. TSW diagram the electromagnetic spectrum and recognize the relationship of
wavelength and frequency to this sequence. (p. 539 - 545)
8. TSW describe the types of reflection and the kinds of images formed by flat,
convex, and concave mirrors. (p. 546 – 549, 570 - 573)
9. TSW explain refraction and the index of refraction and describe the kinds of
images formed by convex and concave lenses. (p. 574 – 578)
10. TSW apply the scientific method in a variety of ways with a focus on one or two
areas of the process. (Appendix in Curriculum Guide)

Introduced and Practiced Outcomes:
1. The Student Will relate the color of an object to the absorption, transmission
and/or reflection of specific wavelengths of incident light. (p. 550 – 553)
2. TSW explain how light is produced by common sources and distinguish lasers
from other light sources. (p. 558 – 562)
3. TSW Describe how reflecting and refracting telescopes, cameras, and compound
microscopes form images. (p. 580 – 585)
4. TSW describe common vision problems and explain how they can be corrected.
(p. 588 – 592)
