. The photodiode will be collecting light from the LED (signal) and other sources like the sun, room lights, laptop screen, etc. (background). We can set the frequency of the LED signal (how rapidly it flashes) higher than these sources and then filter out the background frequencies. The sun provides DC light and light bulbs generally operate at 60 Hz or 120 Hz (50 or 100 Hz in some countries). Therefore, we should use frequencies above these values. Our choices are constrained at the high end as well. What is the maximum frequency we should operate the LED at to get a good signal at the photodiode

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

In an experiment, how can i change human errors? be specific.

Sally turns on her cellular telephone to speak to her friend who is located thousands of miles away. which of the following best describes how such a telephone is able to transmit and receive information? a. the cellular telephone transmits, receives, and encodes information using only sound waves. b. the cellular telephone transmits, receives, and encodes information using only electromagnetic waves. c. the cellular telephone transmits information by electromagnetic waves to a receiver which then encodes them and produces sound. d. the cellular telephone transmits information by sound waves to a receiver which then encodes them and produces electromagnetic waves.
