    Searching for a proper undergraduate project to undertake

    Rich information, I'm going start digging through.

    Searching for a proper undergraduate project to undertake

    I'm not sure about journals though. Cuz I was thinking articles there will be too deep for me. Doctoral level, advanced research. And for equipments I don't have, I could use the university's.

    Can heat transfer break an equilibrium?

    What do you mean by temperature crossing heat capacity.

    Searching for a proper undergraduate project to undertake

    I have a multimeter, and yes I checked some school website, and some other website. I got an idea of possibly reducing bandwidth of tuning circuits to increase the spectrum space but I'm not sure bout the possibility of an undergraduate student cracking that.

    Searching for a proper undergraduate project to undertake

    Summary:: Searching for proper undergraduate project to undertake I'm a physics student, and I was randomly assigned a lecturer that was specialised in optics and electronics. He gave me two topic options to choose from, one was optics, the other electronics. However, I didn't like the...

    Thermal radiation's origin

    Yeah, sorry. Wanted to say all molecules in a material above absolute zero.

    Thermal radiation's origin

    I'm saying that all other forms except radiation is zero. It is said that all molecules above absolute zero emit thermal radiation which are actually photons. The question is, what is the source of the this photons? From the electron? nucleus? Where? And how?

    Thermal radiation's origin

    If a substance gains energy, it's molecules vibrate faster and thus the material increases temperature. My question is if heat lost through any other means but radiation is zero, how exactly does these molecules radiate photons?

    B P-N junction Semiconductors

    First, by saying semiconductor, I think you really mean PN junction diode. Now, drift current is the tiny amount of current that flows when hole/electrons move from where they are highly concentrated to a region of lower concentration. This doesn't say anything about due to application of...

    B Hertz experiment - The Spark

    So, I can create and detect em wave from a 220 V 50Hz ac in my house?

    B Hertz experiment - The Spark

    Hello, so I was reading bout the Hertz experiment in different text and they always say something about the Spark causing accelerated electric charge. So I was wondering, is the spark necessarily for the production of EM waves? If yes, why? Because as I recall, applying an ac voltage should...

    Testing How to perform a major physics experiment at home

    Generally, I love mechanics (which may include fluid mechanics, aerodynamics, or even orbital mechanics), electromagnetics and thermodymics. Nevertheless, I do get interested in electronics, electricity and optics. Yeah, I think you got what I meant the most, but on the basis of electronics and...

    Testing How to perform a major physics experiment at home

    Please, can you give me examples of such kit project or tell me where I can find them. Thank you.

    Testing How to perform a major physics experiment at home

    One may be Hertz experiment where he created and detected em waves. Possibly, the cathode Ray experiment, and others that may have not being famously performed but are a good way of demonstrating a phenomenon.

    Testing How to perform a major physics experiment at home

    Hello there, I am a physics undergraduate and one trying to be very practical. I try to study a lot, to understand the principles and everything and get how all this knowledge came to existence. However, except for the little and not-very-modern experiments we carry out in our school I have no...

    Escape Velocity Confusion

    Yes, you're right. Kepler's method assumes that the body escaping is far less massive than the body it escapes. So, it appears you've answered your own question. Kepler's method is inappropriate because it assumes the lesser mass is the escaping mass. This is clearly stated in the assumptions of...

    Perfect. Thanks

    B Something else besides force?

    And this cleared the confusion. Thank you.

    B Something else besides force?

    Alright, but let me clear my confusions. Say I have a toy ship. If I were to hold the ship on the surface of water(no fraction of ship underwater, zero velocity), then left it to sink. Instantaneously, the force of gravity accelerates the object downward, right? But then according to Archimedes...

    B Something else besides force?

    How about the case of the glue. The book was brought to a stop. If we say the force acted by the glue was greater, that would imply the book is supposed to accelerate upwards. Why did an equal force brought the book to a rest?

    B Something else besides force?

    Why does some accelerating body stop when an opposite force is equal to it and some others will continue at constant velocity?. For example, say a book at some height above the ground is against a wall is released from rest. The book will always slide down even if the friction between the wall...

    Career Choice: In between two opinions

    I want to ask, do you think i should focus full time on this or just let it be something I just know how to do. Thanks.

    Extra magnetic energy

    I may have to experiment to know about battery life.

    Career Choice: In between two opinions

    I am a university student studying physics hoping to chase a career in the field. But recently I discovered my love and talent for explaining science in a basic level people who have no idea what it is that they understand, I also like convincing some unbelievers that science works. Then even...

    Extra magnetic energy

    Oh! So whenever it is being attracted, there's a cost in the battery (for an example)
  29. Zaya Bell

    Extra magnetic energy

    Okay, but does that mean it will cost the battery(for example) an "extra" energy for that attraction or perhaps whether or not there's another object being attracted, their is always that energy loss due to the magnetic field
