About the Experiments
These experiments can be done with the equipment included in the system and other items
such as a protractor, drawing compass, and paper. See each experiment for a specific
equipment list.
1.
Reflection: Study the reflection of plane waves from straight and curved barriers.
2.
Refraction: Study how plane waves bend when they pass from one medium to
another where the wave speed is different.
3.
Diffraction: Determine how a diffraction pattern of plane waves changes as the
slit width of the barriers changes and the wavelength changes.
4.
Interference: For a double-slit interference pattern, determine how the interfer-
ence pattern changes as the slit width separation and the wavelength are varied.
5.
Image Formed by a Plane Mirror: Determine the position of the image formed
by a plane mirror relative to the image distance from the mirror.
6.
Wave Speed: Determine how wave speed depends on frequency and on water
depth.
7.
Doppler Effect Demonstration: Demonstrate the Doppler Effect by moving the
ripple generator at a constant speed in a straight line.
