What is the use of X-ray in Millikan's oil drop experiment? It ionises the oil but what does the ionisation help in? If it creates charge, then the oil's charge keep on increasing it creates error in calculation as the oil drop is attracted upward after sufficient amount of charge.

Is light wave always linearly polarized?

If you find out the data and calculate its position and says that the electron is there, the electron is not now, there , it had reached somewhere else...

You know, position means where it is right now. Let's take an example of electron. There are many factors which accounts for the uncertainity:- 1) If you calculate the position of the electron, it escapes out from the present position to the next one while you are calculating and it always...

I am amazed why we should use Euclidean transformation of spacetime and Lorrentz transformation of Spacetime for this problem. In what sense it is different than measuring relative velocities in case of earth. There is a frame of reference i.e B (in rest) like Earth while we do some experiment...

Einstein's Theory of Relativity is based on two principles and one of them says "No matter how fast you are moving, the speed of light always remains the same for you i.e. c". For example, if you are traveling at the rate of 2*108 m/s, relative to earth, then essentially, the relative velocity...

Atoms in solid are more closedly packed as compared to liquid and gases. But we exert more force, some solid gets compressed but liquid doesn't, why? If atoms are loosely packed in liquid than solids, liquids should get compressed...

We all very well know that, Earth has been made 4.5 billion years ago. Suppose, we are to explain the age of the star and we say that it is 27 billion years old. One year is the duration of time taken by the Earth to revolve around the sun once. Before the origin of Earth, how could we explain...

We know that the mass of anybody turns to zero as it gains the velocity of light. From Einstein's Mass-Energy relation, E=mc2 so that, m=E/c2 It is clear that mass is directly proportional to energy. For a body to gain light's speed, we have to apply...

It doesn't give the solution to my problem. Why is the work done counted double?

On the way to prove 1st law of thermodynamics, you consider a system having initial energy E1. Then, you supply heat q to the system. Some part of the applied heat is used for doing work. Then, again you consider the final energy (E2) of the system to be: E2=E1+q+w where w is the...

So, if colour is the function of the wavelength, why don't color change when wavelength changes?

By De-Broglie,light also exibits matter property. According to him, wavelength=planck's constant/ momentum. And again momentum is the product of mass and velocity. We again know that, mass of light i.e. photon is zero. Then from De-Broglie's equation, is the wavelength of light infinity? If...

As far as I have understood,light is the fastest thing in universe. But the most important thing is that it is only in the sense of our available technology and science. Scientists had already mentioned that, during the big bang, initially matter traveled and scattered at a great speed; even...
