**PHYS 222Physics II (GE)Credit hours (4)Prerequisites: PHYS 221**

Topics are studied utilizing calculus.

**Detailed Description of Course**

The students' study of mechanics, the subject matter of PHYS 221, is extended to continuous
media and wave motion. A brief treatment of heat and kinetic theory is then included.
This occupies approximately the first quarter of the course. The middle half of the
semester is devoted to electricity and magnetism. This section contains the most extensive
use of calculus, in the discussion of the laws of Gauss, Ampere, and Faraday. The
Maxwellian synthesis then makes the connection between electromagnetism and light,
and the remainder of the course is devoted to studying geometrical and physical optics.
The major areas which are covered are:

1) Fluids, including Archimedes' principle

2) Waves, including the principle of superposition and standing waves

3) Heat, including specific heat, thermodynamic work, and the first law of thermodynamics

4) Kinetic theory of ideal gases

5) Coulomb's law, the electric field, Gauss's law

6) Electric potential energy and potential

7) Ohm's law and simple circuits

8) Magnetic fields, Ampere's law

9) Faraday's law

10)The Maxwellian synthesis, the electromagnetic spectrum

11)Geometrical optics: reflection, refraction, mirrors, lenses

12)Physical optics: interference and diffraction

Detailed Description of Conduct of Course

During the lecture periods, the basic principles of mechanics are presented and explained.
Every effort is made to relate these principles to the students' actual experiences.
Students are encouraged to participate in classroom discussion by asking questions
or by suggesting illustrations, applications, confirmations, or apparent violations
of the stated principles. As much time as possible will be devoted to problem solving.
The instructional strategy used here is example and practice. Detailed solutions to
typical problems are presented in class, with extensive explanation of the motivation
behind the steps followed in these solutions. The student is then encouraged to understand
the solution process, rather than to simply memorize the specific solutions themselves.
Homework problems allow the students to practice what they have learned. They are
strongly encouraged to do many problems and to wrestle with problems whose solutions
do not come easily. The lab exercises are designed to reinforce the student's understanding
of the basic physical principles which are discussed in the classroom and which are
applied in the problems. They also serve to introduce the student to experimental
procedures, data analysis, and the drawing of conclusions. Students work in groups
of 2 - 4. The instructor or an assistant circulates about the room in order to observe
the students' procedures, provide assistance, or pose questions for further investigation.
A lab report must be submitted for each lab exercise.**Goals and Objectives of the Course**

1) Students will be introduced to physics - what it is, what it does, how it does
it.

2) Students will learn the principles of classical mechanics and how to relate
them to real-world physical situations.

3) Students will improve their problem solving ability, in particular, their
ability to solve quantitative problems which are posed verbally.

4) Students will improve their experimental skills, in particular, their ability
to take data, analyze it, and draw conclusions.

Core Curriculum Objectives (Goal 6: Physical and Natural Sciences)

Radford University students will understand the methodologies of scientific inquiry,
think critically about scientific problems, and apply principles of a scientific discipline
to solve problems in the natural/physical world.

Radford University students will be able to:

1) Distinguish between findings that are based upon empirical data and those that
are not.

2) Apply scientific principles within the context of a specific scientific discipline
to solve real world problems.

Assessment Measures

Progress toward Goals (1) and (2) above is assessed through informal discussion with
students during labs and office visits, and through classroom participation. Goal
(3) is assessed through homework problems, tests, and the final exam. All tests and
the final exam contain problems only. The students are expected to show all significant
work and will receive substantial partial credit for the correct plan of attack and
for the correct application of relevant equations. Clearly, students' performances
on these problems also measure their understanding of the physical principles referred
to in Goal (2). Students' lab skills are assessed through observation during the lab
period and through the submitted lab reports.**Other Course Information**
