The diagram I posted was meant for amplitude modulation and not phase angle modulation.
In case of AM, the carrier is supposed to be changed in accordance to the instantaneous value of the modulating voltage. So Vc should be changing on the X axis.
So should I understand that the sinor is the...
Thanks a lot mezarashi for the lucid explanation. It dispelled some doubts but a few more still remain.
Okay, So in the attached diagram, the Vc is totally real therefore it is on the X axis. And the length of vector Vc is it's amplitude. And it has no time component. (This is the phasor...
Okay, I guess that the thing is working like a rack and pinion apparatus. Should there be no friction,the bicycle would not turn.
But what I am not able to grasp is how the velocity components are resolved in such a case and what happens when the handle is turned by a certain amount? :(
The component of a force in a perpendicular direction is given by F Cos 90 and is 0.
But when one rides a bycycle and stops paddling before and after taking a 90degree turn, the bycycle continues to move forward.
What might be the explanation?
So If I take a picture of a spot on a surface, the speckles may show up? I will ty it and post it here. And the speckles seem to move as I move the beam. They do not vhange their relative position.
An Intresting thing about laser beams that I noticed is that you always find thousands of small dots in the spot that is formed by a laser beam on the surface? What could it be? Maximas of light beams caused by constructive interferences? I am yet to find out. Please let me know if you have any...
