Learning Objectives:

After completing this course, students should be able to:

• Describe wave motion, including differentiating between transverse vs longitudinal waves, and standing vs progressive waves.
• Derive and solve the equation for a propagating wave and a standing wave.
• Describe the energy transported by a wave and the resonance condition,
• Explain Huygen's Principle and perform calculations involving the Doppler effect.
• Perform calculations related to the concept of superposition, including interference & diffraction.
• Apply concepts of temperature and heat as energy to solve problems concerning the transfer of heat and effects of heat on systems.
• Apply 1st and 2nd laws of Thermodynamics to systems to solve problems involving work, heat, and thermodynamic cycles.
• Perform and interpret the results of simple experiments and demonstrations of physical principles.
