  1. electromagnetic radiation - Why does high frequency have high energy ...

    Nov 21, 2022 · 15 The individual photons have more energy, but this does not mean the total energy in the wave has a higher energy. There are many examples of a high frequency, but a lower amplitude.

  2. filter - why is noise always a high frequency signal ? what then is ...

    Jan 21, 2016 · 3 while designing signal conditioning circuits for sensors , we design low pass filters to remove high frequency noise. why can't noise be a low frequency signal or what will its frequency be ?

  3. Why are capacitors high-pass / low pass frequency elements?

    Dec 11, 2020 · With low frequency signals, little current flows in the capacitor, little voltage drop across the resistor, so most of the low frequency signal voltage appears on the capacitor. As you can see, …

  4. What ties high frequency electromagnetic waves to short wavelength …

    Oct 19, 2021 · Why is it not possible to have waves with high frequency (high energy) and great wavelength and converse? What physical quantity ties frequency to wavelength in an inversely …

  5. Why do higher frequency waves have better penetration?

    This question is probably better suited to the physics stackexchange. In general though, the penetration of an EM wave is determined by the absorption of whatever you're trying to penetrate. The very high …

  6. Why does a higher frequency mechanical wave have more energy?

    Sep 16, 2023 · For more proof, you can refer to the general relationship that the average rate of energy transfer (i.e., the speed that the waves are traveling) is proportional to the square of the amplitude …

  7. How to choose right PWM frequency for LED?

    Aug 18, 2013 · The higher the frequency, as well as longer 'on' pulse width will give the most consistent light. Choice of frequency now depends more on how many different widths you wish be able to …

  8. homework and exercises - How do I calculate the low frequency and …

    How do I calculate the low frequency and high frequency gains of an op amp amplifier? Ask Question Asked 8 years ago Modified 7 years, 11 months ago

  9. Why does an inductor behave as a capacitor at high frequencies?

    Jan 26, 2012 · As the frequency increases, the impedance of the inductor increases while the impedance of the parasitic capacitor decreases, so at some high frequency the impedance of the …

  10. Using normal diodes to rectify high frequency waveforms

    Jan 27, 2014 · Using a high frequency diode to rectify a low-frequency waveform will produce even less heat by reverse-recovery than in case with a low-frequency diode, but in both cases it will be …
