I apologize for posting something like this here, I understand that it does not follow the given guidelines, however I am unable to find any good resources for myself. I am taking the Introductory Physics MCAS test and I need to learn and understand the following standards that I cannot quite wrap my mind around: “Standard: 5.1 - Recognize that an electric charge tends to be static on insulators and can move on and in conductors. Explain that energy can produce a separation of charges.” “Standard: 5.5 - Explain how electric current is a flow of charge caused by a potential difference (voltage) and how power is equal to current multiplied by voltage.” “Standard: 6.2 - Describe the electromagnetic spectrum in terms of frequency and wavelength and identify the locations of radio waves, microwaves, infrared radiation, visible light (red, orange, yellow, green, blue, indigo, and violet), ultraviolet rays, x-rays, and gamma rays on the spectrum.” I've managed to simplify many of the other standards that I don't understand in order to learn them in a quicker and more efficient fashion, however, I do not understand these Standards on a level that will allow me even to simplify their wording, or find online resources for learning about what they speak of. I was hoping that someone here could direct me to an online resource that could teach me about what is mentioned in the listed Standards, or simplify their wording to a point where I can understand them even with the basic knowledge I have, allowing me to learn what I need by myself. Any help will be greatly appreciated, thanks!
