Bookmark or Share- High frequency blinking LEDs and sensor for that - Electrical ...A CdS photocell would not be suitable for high frequency light sensing: The rise + fall time for common CdS cells are of the order of tens to hundreds of milliseconds. For instance, this randomly picked datasheet mentions 60 mS rise time and 25 mS fall time. Thus the highest frequency it can handle is below 11 Hertz.
- What is the highest possible frequency for an EM wave?A wave with that wavelength would have a frequency of $\approx 6.2\cdot 10^{34}\,\text{Hz}$. A gamma ray typically has a frequency of $>10^{19}\,\text{Hz}$. Since the energy of a photon is directly proportional to its frequency, this theoretical upper bound would require vastly more energetic processes than those we presently conceive of.

- How do smaller capacitors filter out higher frequencies than larger ...Finally, the placement and connection of the cap affects the inductance too. Long traces add to the cap's own ESL, shifting the resonance point down and increasing impedance at high frequencies. To avoid this, the smaller, high-frequency caps are placed closest to the noise source. This Murata appnote explains this in more detail.
- Why does an inductor behave as a capacitor at high frequencies?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 capacitor is much lower than the impedance of the inductor, which means that your inductor behaves like a capacitor. The inductor also has its own resonance frequency.
