All I am saying is that, when a part of a circuit gets connected to earth, only that part of the conductor gets the potential zero. That part that is connected to Earth is what I call the "spot". And behind or in front of that "spot" is meant parts of the circuit that is front or behind the...

Okay, so you are telling me that the resistance in other devices than resistors is not reasonably constant when applying different voltages? Or even the same voltage and therefore the only formula describing the power correctly is the first. Well what about the second question? Can you...

Hello! I have a few questions that need answers. They are just simple thoughts. First of, its is said that the formula P = UI can applied to the energy being transformed every second over any component. But the formula P = (U^2)/R and the P= (I^2)R only can be applied over resistors...

I have another question; it’s about resonance in air columns when resonance appears in a air column with a open end. Its seems that the sound wave reflect at the ending between the open air and the air stored in the column. But if it’s so, then how can one explain motion antinodes that appear at...

Hello! This quote is from my physics textbook “ From the formula speed = lambda * Frequency we can conclude that the reduction in wavelength is because water travels with a slower speed in when moving from deep to shallow water” This does not make any sense at all. You can’t explain...

I still have not recived any acceptable answer to the question.

Hello Hombre What i mean was the two light waves that meet on a screen and cause an interference pattern. A dark spot on the screen, this two waves cancel each other on that particular spot (on the screen, not a mirror), but the two waves don’t completely destroy each other there. They...

I would like to understand exactly how to principle of superposition works. I don’t think its so simple that you could imagine as first. A mechanical wave doesn’t need a physical movement to spread thorough a medium, and it can not be stopped by physically stopping the movement of some of...

Thanks for your replies, some of the things you hade said has been useful. It was stupid to question the roll of the peak through, and I has been very useful to what light waves are made of. As I understand it from your replies, my theory about how light waves should behave like water...

I have got another question, if light can be described as a wave. Then how can the wave top and the wave bottom be described, I mean what sort of qualities do they have? Is it the wave top that creates light? What does the wave bottom do then? Sorry for my foolish question, but I don’t think...

Hello! Here is something though that has been haunting me recently. If lights from two different sources meet and the distance that the lights have traveled from each source differs a half of the wave length of the one photon the light waves will “destroy” each other and if they meet on a...

Come on, answer please. If you don't understand what i mean with the question, don't hesitate to ask me to be more precise! The question is again: Can a mechanical wave travel through some kind of physical abstacle that temporerly stops the physical movment of the wave to resume its motion again...

This is a question about mechanical waves. As i understand it, there can be many different types of mechanical waves, but its is not allways necessary to actually make a physically motion of one harmonic oscillator (a particle, or a part of the medium that the mechanic waves travels throw) to...

Its is now done. The main problem was the distance between the the screen and the splits.

dont work. It just can't be done, don't matter how you want to put it, to get interference the space between the slits need to be about the same as the wavelenght of the light, and that's 650 nanometers. Tell me, how I am going to even come close to such a slit? I have tried the with cards and...
