Surface tension is a property of liquor. Due to this property liquid surface behave like a membrane and hold object on it. One of popular application of this topic is spherical shape of rain drop. We discuss this in detail in our post surface tension in physics.

Amazing information

Transformer is a device which is used for changing the voltage of an AC power source to higher or lower value. Principle of transformer in physics It is based on principle of mutual induction that is an emf is induced in a circuit due to a current changing in a neighbouring circuit.

Transformer is used for transmission of electricity. Amazing topic.

Capillary tube and capillarity in physics topic is explain in detail.

Here we discussed about lattices vibration in details.

Bragg's law hepl us to understand basics of crystal structure. It explains interplanner spacing in details.

Bragg's law

Over 900,000 bibliographic records, including 360,000 fulltext documents of interest to people working in particle physics and related areas. Covers preprints, articles, books, journals, photographs, and much more.

As modern cosmologists rely more and more on the ominous "dark matter" to explain otherwise inexplicable observations, much effort has gone into the detection of this mysterious substance in the last two decades, yet no direct proof could be found that it actually exists. Even if it does exist, dark matter would be unable to reconcile all the current discrepancies between actual measurements and predictions based on theoretical models. Hence the number of physicists questioning the existence of dark matter has been increasing for some time now.

Here we discussed Coulomb's law of electrostatic in details.
