    Electromagnetic Radiation and Mediums

    1. Homework Statement Hello there! I have a couple of questions regarding light(EMR) and how it behaves when moving from one medium to another. From what I understand, the frequency of any light wave, when it moves from one medium to another, stays the same. As a consequence of this, the...

    Electromagnetic Waves

    Thanks for the reply! Unfortunately, I am a bit more confused now. I understand what you mean by charge distribution in a current carrying wire but what is a crystal ion and what if we had a charged particle flowing through space? There would be no charge distribution since an electron with...

    Electromagnetic Waves

    Thank you so much for your response. Yes, after writing my previous question(s), I started researching a little more on what electric and magnetic fields really were and I came across the Lorentz transformation which dealt with time dilation and length compression. Basically, from what I...

    Electromagnetic Waves

    So, as a light waves moves through a vacuum, the changing magnetic field creates a changing electric field and the process continues, correct? Also(a bit off topic), what is it about a magnet (a bar magnet for example) that causes a continuously produced magnetic field? Are charges moving within...

    Electromagnetic Waves

    1. Homework Statement Hi there! I am currently taking physics and we are in the process of learning about electromagnetic radiation. I am a bit confused as to how exactly an electromagnetic wave is produced. I understand that a periodically oscillating charge produces and oscillating magnetic...

    Cross Product of Magnetic Field(B) and Velocity of Charged Particle(v).

    So your telling me that if I was to (hypothetically) place a proton or electron in a magnetic field, It would experience no force simply because its velocity is zero? That doesn't make sense to me. What could velocity possible have to do with the amount of force acting on a charged particle in a...

    Cross Product of Magnetic Field(B) and Velocity of Charged Particle(v).

    1. Homework Statement Hi there. I am currently taking physics 30(algebra physics course) and we are in the electrostatics unit. I am curious as to why, when trying to find the force acting on a charged particle moving perpendicular to a magnetic field, the force results in a direction that is...

    Electric Potential Energy

    1. Homework Statement \ Hi there! We are currently studying forces and fields in physics and we are in the electrostatics chapter. I am having a bit of trouble fully understanding electric potential energy. The book states that electric potential energy is defined as the work required to move a...

    What is charge really?

    Are you asking me? Ions have electric charge because they have lost or gained electrons with respect to the original atom. Charge represents how positive or negative an ion is relative to its' neutral atomic state. This, however, does not explain why an object that is solid can have such...

    What is charge really?

    1. Homework Statement The problem is that I don't understand what causes an object to become positively or negatively charged. I know that, in chemistry, ions represent charges in voltaic cells. For example, cations become reduced and their electrons travel to the anode. This creates a negative...
