By the end of this unit, a successful student will be able to:
- (27.3) Distinguish between mechanical and electromagnetic waves. MSTE Phys 4.2
- Recognize that electromagnetic waves are transverse waves MSTE Phys 6.1
- (27.2, 27.3, 27.4) Recognize that electromagnetic waves travel at the speed of light through a vacuum. MSTE Phys 6.1
- Use mathematical representation to support a claim regarding relationships among the frequency and speed of waves. (NGSS HS-PS4-1)
- (27.3)Describe the electromagnetic spectrum in terms of frequency and wavelength and identify the location of radio waves, microwaves, infrared radiation, visible light (red, orange, yellow, green, blue, indigo, and violet), ultraviolet rays, x-rays, and gamma rays on the spectrum. MSTE Phys 6.2
- (27.1) Recognize that light behaves both as a wave (reflection, refraction, interference) and as a particle (photons).
- (27.4, 27.5) Describe how light interacts with different media on an atomic level and on average, slows down when traveling through a medium, how some materials such as glass a transparent to some wavelengths yet absorb others, and why some materials such as metals are reflective.
- (28.1, 28.2, 28.4) Recognize white light as a combination of all visible colors and how sunlight is brightest in the yellow-green portion of the spectrum
- (28.8 – 28.10) Explain why the sky is blue, why clouds are white, why sunsets are red and why the sea is green in terms of scattering, reflection, and absorption.
- (29.1-29.5) Explain what is meant by reflection including the law of reflection.
- (29.6-29.9) Explain what is meant by refraction, how it relates to wave speed, and how it can lead to mirages
- (29.10-29.11) Describe how dispersion of different colors of light relates to the difference in speeds of those colors in a medium and how that leads to such phenomena as rainbows and spectra from prisms
- (29.12) Define what is meant by the critical angle and explain how it relates to total internal reflection
- (29.3, 30.2) Compare virtual images to real images.
- (30.3) Use geometric optics to determine the focal length of lenses
- (30.5, 30.6) Compare the telescope, camera, and human eye
- (30.7) Explain nearsightedness and farsightedness in terms of eye-shape and image location.
