since its quantum mechanics and relativity, pls be a little clear:
1. Consider yourself to be a photon moving away from the earth into outer space. Will you be
surrounded by darkness or by light?? How does the motion of the earth appear to you??
2. The positively charged nucleus is surrounded by electrons that are negatively charged. So now,
what keeps the electrons from falling into the nucleus? What would Heisenberg’s uncertainty
principle have to say if the electron did spiral into the nucleus?
3. We know from the world’s most famous equation E=mc2 that energy and mass are
interchangeable now, as the body accelerates, the velocity increases tremendously, the body’s
energy increases. So according to E=mc2 the body gains mass. So tell me now do the individual atoms
gain mass by themselves? Or does the system gain mass as a whole? Redefine mass in such a way
that it suits the above statement
4. When a polarizer is placed in a polarized beam of light, the intensity (I) of the light that passes
through is given by the relation I=I0Cos2è
Where Io is the initial intensity and è is the angle between the light's initial polarization direction
and the axis of the polarizer. Now, it is well known that intensity is a direct measure of the number
of photons. On that note, for an angle of èi = 45o, the intensity is halved. So, if there were, say, 500
photons initially, the resultant would be 250 photons. Similarly, 20 photons would become 10.
Suppose one photon enters the polarizer, what would you expect?! How do you explain the Physics
behind it?
5. The fluorescent bulbs (commonly called tube lights), have a rating of 6000K given to them. What
exactly does this rating mean?? If it were really at a temperature of 6000K, we would not be able to
sit in the room. So how exactly is this temperature rating given?
