TEXTBOOK:  Chapter 13, Sections 13.8 to 13.13, pages 423 - 432.

OBJECTIVES:

• Differentiate between transverse and longitudinal waves.

• State the cause of wave motion and its purpose.

• Differentiate between a pulse and a wave.

• 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.

• State and explain the formula for determining the velocity of a wave in a stretched string and use this formula to solve problems.

• Use data analysis to determine the exact relationship between two variables that are related.

• Observe and describe 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.

• 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.
