PHY 121 Week 7
| |
Main Objectives:
 | Waves
 | Definition of
waves
|
| Properties of
waves (definitions and applications, such as refraction being used to explain how prisms
work and applications of scattering to why the sky is blue)
|
| Understanding
what causes refraction
|
| Relationship
between speed, wavelength and frequency
|
| Speed of light
in a vacuum is 3 x 108 meters/second.
|
|
| Particle Model
| Why was the
particle model introduced
|
| Describe the
particle model
|
| Be able to find
the energy of a photon or its frequency given the other one
|
| How can light be
both a wave and a particle
|
|
| Electromagnetic
Radiation
| What causes
electromagnetic radiation
|
| Be able to list
the types in order of wavelength and give a brief description of each
|
| Discuss thermal
radiation curve and how it is related to the temperature of the object
|
|
| Temperature
Inversion
| What is it and
why is it a concern
