Great explanation, but how do you prove that theta prime 2 = theta 2? I cant seem to find an angle that adds to both to equal them to 90 degrees
@matthewjohnson2554 Ай бұрын
@@maaarx1158 Hi, it’s similar to how you show that theta1 prime = theta 1. You can just use, say, B as the angle between the second theta2 I drew and the horizontal line, and you know they have to add up to 90 degrees. Also you can also see that B + theta2 prime +the 90 degree corner must = 180 for a triangle. Therefore theta2 prime + B = 90, therefore theta2 prime = theta2.

smart people should ask this in low pass filter in order to understand why his explantion is wrong* : 1. the capcitor is fully charged when the input frequency is low like 20hz, ok and simple to understand, nothing complex... then 2. when frequency input is very high like 500hz then the capcitor just dont fully charged but way less because of the speed of the input frequency...mean the capacitor start to charge him self and suddnely the source go off state, hence not fully charged, in different words.... which mean according to his explantion in the first situation the capcitor is fully charged and in the second example the capcitor is just dont fully charged lets say half.....ok up to this point everything is simple to understand...here the problem comes.... then someone smart ask but hi, the frequency stay the same its just the capcitor dont charged fully and the output of the capcitor also the same charge he charged... then how the hell its filter high frequencies ?????? low pass filter mean this...for example the input is 1000 hertz(1khz) mean 1000 cycles per second and after it pass the circut its 200 hertz, mean 200 cycles per second, mean less cycles per second...which mean ......that the capcitor dont charged every time but miss alot of the cycles and hence the output its lower frequency...other wise according to his explantion you dont filter out frequencies...but just output half the input, but frequency is the same

@@matthewjohnson2554 I found in my textbook (Briggs 3rd ed.) p 1108, *k* is the z-axis unit vector = <0,0,1>, and to find a unit vector *n* in the xy-plane normal to C and orthogonal to *T* (unit tangent vector I think) and *k* , then *n* = *T* x *k* (cross product) Maybe this is what's going on.
@matthewjohnson2554 3 ай бұрын
@@EmpyreanLightASMR Hey so the k hat is there to specify that the curl of a vector field in the x,y plane would be defined in the perpendicular z plane. If you prefer to ignore the k-hat that’s fine. The explanation I’m giving doesn’t really depend on the k-hat, it just specifies the curl is technically in the z direction.

Great explaination! Additionaly it would have been interesting to change the value of the resistor. My question I ask myself is: which frequency should I set the filter for a DC Signal to filter out noise on the ADC input of my esp8266. Can it be too low? Ist it better to use a big resistor or a big capacitor to get a specific frequency?

awesome,but how does compression work with light if electromagnetic waves do not need any particle to propagate?i mean how do we see this effect with electromagnetic waves?
@matthewjohnson2554 8 ай бұрын
The Doppler effect is based only on the speed and the wavelength of the wave. I suppose though it would also be dependent on how fast the wave travels. Sounds travels at a certain speed through air just like light travels at a certain speed depending on the index of refraction.
