Chapter 5 – Waves and Light
Learning Objectives
Objectives: By the end of this chapter, students should be able to:
1. Draw a transverse wave and identify its amplitude, period, frequency, wavelength, nodes, crests, and
troughs.
2. State the difference between transverse and longitudinal waves and be able to give examples of each.
3. Given the equation: v = d/t, where v = velocity, d = distance, and t = time, solve for any variable
given the other two.
4. Given the equation: v = f, where v = wave velocity, = wavelength, and f = frequency, solve for
any variable given the other two.
5. Given the equation: T = 1/f, where T = period and f = frequency, solve for any variable given the
other.
6. State how the frequency and wavelength of sound waves is affected when produced with an open-end
pipe/tube vs. a closed-end pipe/tube.
7. State how changing the tension of a string affects the frequency and wavelength of the sound wave
the string produces.
8. Know how to measure angles of incidence and angles of reflection for flat and curved mirrors.
9. Know that a light wave will be bent when it travels from one medium to another medium of different
refractive index (index of refraction).
10. Know how to measure angles of incidence and angles of refraction when light passes from one
medium to another.
11. Know that the electromagnetic spectrum consists of waves from long wavelength to short
wavelengths (radio waves, microwaves, infrared waves, visible light, ultraviolet, X-rays, and gamma
rays).
12. State that the visible light spectrum consists of the colors ROYGBIV (red, orange, yellow, green,
blue, indigo, violet) in order of increasing frequency and energy.
13. State the fundamental difference between a mechanical wave and electromagnetic (EM) wave.
14. State the definitions of and give examples of supersonic, subsonic, ultrasonic, and infrasonic waves.
15. Draw a ray diagram for an object for a flat (plane) mirror, locate its image location/orientation, and
determine whether the image it produces is real or virtual.
16. Define and draw a tangent line and a normal line for a curved mirror or lens.

17. Define and find the focal point for a concave and convex mirror.
18. Draw a ray diagram for an object produced by a concave or convex mirror, locate its image
location/orientation, and determine whether the image it produces is real or virtual.
19. Draw a ray diagram for an object produced by a concave or convex lens, locate its image
location/orientation, and determine whether the image it produces is real or virtual.
20. Given the mirror equation: 1/f = 1/d i + 1/d o , where f = focal length, d o = object distance, d i = image
distance, solve for any variable given the other two.
21. Given the lens equation: 1/f = 1/d i + 1/d o , where f = focal length, d o = object distance, d i = image
distance, solve for any variable given the other two.
22. Know that the wave speed of ANY electromagnetic wave in a vacuum is the same (i.e. 3.0 x 10 8
[m/s] or 186,000 [mi/s]).
23. State the difference between color mixing and color subtraction with respect to light and pigments
(paint) and explain whether a certain visible color is produced via color addition or color subtraction.
24. Draw a ray diagrams for a reflector and refractor telescopes and be able to qualitatively explain their
operation.
25. Draw a ray diagram for a microscope and be able to qualitatively explain its operation.
