Interactive Activity: Amplitude and Frequency
This activity demonstrates a moving sine wave that allows for amplitude and
frequency changes.
|
 | |
|
Interactive Activity: Amplitude, Frequency, and
Phase
This activity draws a dynamic wave calculated from user input.
|
 | |
|
Interactive Activity: Analog to Digital Conversion
In this
activity, the student will take samples of an analog signal and turn it into
digital form.
|
 | |
|
Interactive Activity: Calculating Decibels
This activity allows the student to enter values for Power final and Power
reference, then calculates for decibels.
|
 | |
|
Interactive Activity: Using Decibels
This
activity allows the student to enter a value for the decibels and a value for
the reference power resulting in the final power.
|
 | |
|
Interactive Activity: Electromagnetic Fields and
Polarization
This activity includes a series of animated, graphical explanations of EM
fields and polarization.
|
 | |
|
Interactive Activity: Propagation of Light in
Matter
This activity demonstrates how light slows down through different
materials.
|
 | |
|
Interactive Activity: Electromagnetic Calculator
This activity allows students to enter values for frequency and wavelength
to calculate the speed of light.
|
 | |
|
Interactive Activity: Electromagnetic Spectrum
This activity allows the student to scroll through the EM spectrum by moving
the mouse to the left or right over the graphic.
|
 | |
|
Interactive Activity: Fourier Synthesis
In
this activity, the student will draw sine waves by selecting the amplitude,
frequency, and phase of each.
|
 | |
|
Interactive Activity: Tone Generator Modulation
This activity plays frequency sounds and modulated sounds.
|
 | |
|
Interactive Activity: Digital Modulation

|
Interactive Activity: Optical Refraction
This
activity shows how refraction works in different materials (starting from a
vacuum).
|
 | |
|
Interactive Activity: Law of Reflection
This
activity animates how angles affect reflection.
|
 | |
|
Interactive Activity: Multipath
This activity demonstrates how a laptop transmits signals and how those
signals can be received by the Access Point.
|
