CHM 111 Chapter 6 Worksheet and Study Guide Purpose: This is a guide for your as you work through the chapter. The major topics are provided so that you can write notes on each topic and work the corresponding problems. This should serve a s a study guide as you go on to do the problems in Sapling and take the quizzes and exams. The Problems are embedded in the Topics and Space for Notes Topic 1: Section 6.1 Electromagnetic Energy By the end of this section, you will be able to: Explain the basic behavior of waves, including travelling waves and standing waves Describe the wave nature of light Use appropriate equations to calculate related light-wave properties such as period, frequency, wavelength, and energy Distinguish between line and continuous emission spectra Describe the particle nature of light Relevant equations: c = υλ E = nhυ Know that light is a wave or a particle. Be able to use the equations: c = υλ E = nhυ Be able to explain that light is quantized (an understand quantized!). Notes: 6.1.1 What is a wave? 6.1.2 Explain the difference between traveling wave and standing wave.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
