# Ch 17: Modern Physics & Nuclear Physics

Watch video lessons on modern and nuclear physics and learn about photons, mass-energy conversion, radioactive decay and more. These video lessons are short and engaging and make learning easy!

## Modern Physics and Nuclear Physics - Chapter Summary and Learning Objectives

Watch video lessons in this chapter and learn about the photoelectric effect and photons. You'll study the wave nature of matter and learn how the Bohr model is related to atomic spectra. The instructors who lead these lessons teach you about the relationship between mass and energy and explore different types of radioactive decay and how they affect the nucleus. At the end of this chapter, you'll be familiar with:

• Applications for linear momentum conservation
• Mass-energy conversion
• Fusion and Fission
• Carbon dating

Video Objectives
Photons and the Photoelectric Effect Relate the energy of a photon in joules to its wavelength and the linear momentum of a photon to its energy or wavelength.
The Wave Nature of Matter Explain how matter exhibits wave characteristics described by the De Broglie wavelength.
The Bohr Model and Atomic Spectra Draw the Bohr model of the hydrogen atom and explain how it relates to atomic spectra.
Mass and Energy: Description and Interchangeable Relationship Discuss the theory of relativity and how it states that mass and energy are interchangeable.
Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy Explain the relationship between mass and energy. Define mass defect and nuclear binding energy.
Types of Radioactive Decay and Their Effect on the Nucleus List the different types of radioactive decay and describe their shielding requirements and effects on the nucleus.
Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs Perform calculations involving half-lives and use a graph to determine the half-life of a radioactive sample.
Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry List and explain applications of radioactive nuclides.
