modulation of waves (1 Viewer)

[sly_skittle]

Has anyone done an experiment for this part of the syllabus- we didn't do one in class?

we did experiments regarding the effectiveness of amplitude / frequency modulated waves (e.g. seeing if in different locations the quality of each types varied using a radio) and the different types of reactions that waves enounter such as scattering, reflection, diffraction etc. using a pan filled with water,several obstacles in the water to deflect the waves, and a ruler to create them...sounds riveting aye?
Goodluck with the HSC

if you do a google search there is a simulation I use with my students because not even the physics staff could help me

just use an ECG?
hook up a microphone and talk into it
the carrier wave changes
this is amplitude modulation
then for frequency u set it to frequency modulation
the amps are the same but frequency changes

don't you meen a CRO?

Imo, I think that's what the OP meant to say. lol way to revive a long dead thread by the way! :rofl:
