TEXTBOOK: Chapter 12, pages 452 - 465.
OBJECTIVES:
Distinguish between mechanical and electromagnetic waves; between transverse and longitudinal waves; give an example of each type of wave.
State the cause of waves motion and its purpose.
Distinguish between a pulse and a wave; between compressions and rarefactions.
Define wavelength, frequency, period, and amplitude as they refer to waves.
Derive the equation defining the relationship between velocity, wavelength, and frequency of a wave and use it in solving problems.
State the relationship between the frequency of a wave and its wavelength for a given medium.
State the relationship between amplitude and energy in a wave.
Describe what affects the speed of a wave.
Predict how a given pulse will be reflected by the fixed end or the free end of a spring.
Perform an experiment using a slinky to observe what happens to the wavelength, frequency, and velocity when waves pass through a boundary.
Draw a diagram showing the reflection of a straight line striking a straight obstacle, both straight on and at an angle, and from this drawing state the law of reflection.
Draw a diagram showing how a straight wave is reflected from a curved obstacle and how a curved wave, originating at the 'focus' is reflected from a curved obstacle.
Observe the phenomenon of refraction in a ripple tank and describe what occurs in refraction.
Draw a diagram showing how straight waves are diffracted by a small opening in an obstacle. State how the size of the wavelength affects diffraction.
State how waves affect each other and the medium when they meet.
Distinguish between objects vibrating in phase and out of phase.
Distinguish between constructive and destructive interference.
Determine the resultant displacement of two waves acting on the same particle in a medium by using the principle of superposition.
Locate on a diagram the node and the antinode and determine the wavelength of the interfering waves if given dimensions on the diagram.
Draw a diagram showing the interference pattern between two point sources in phase and to locate both the nodal lines and the lines of maximum constructive interference for a two-dimensional surface (e.g. water).
Describe
the formation of standing waves.
