• What is mass of light?
  
• ```why does red light travel faster than violet light , though violet light has more energy (in glass)? plz give a simple answer which can be understood by a 10th class student.
  
• What are bosons?
  
• Why photon doesn't have antiparticle?
  
• What is the approximate value of pi?
  
• If lens has different focal length for different colours then how do we see things multicoloured?
  
• What is (√-1)²?
  
• If the fundamental theorem of algebra is correct , then why i am bein taught discriminant less than 0 for quadratic equations mean no real roots ? (i m a 10th standard student who was taught about polynomials and quadratic equations)
  
• Please amswer ASAP , its urgent . what will be the remainder when #[{7^365-1}/6]# is divided by 5? i know that the divident will be a whole number so plz just write numeric value of answer . i need to confirm..
  
• Consider a Geometric progression #1,7,49...7^364# . find the remainder when sum of this g.p is divided by 5.?
  
• I wonder 'image is formed by intersection of 2 light rays' . Can't it be a single light ray to form an image ? Some sources do suggest that a single photon can form image
  
• Help in trignometry! (?)
  
• What is 0.5! And how do you find it (can it be found without calculus)?
  
• Prove: #e^(i pi)+1=0# "?"
  
• Find complex values of #x = root (3)(343)# ?
  
• Complete reaction #PbO+C ->Pb+?# Some sources suggest #CO_2# while others #CO#. Do they exist in equilibrium?
  
• In an electric motor, say it has only one coil. The coil spins because of current in it. So, is there any electromagnetic induction process occuring simultaneously?
  
• What can be the least energy of a system as per Heisenberg's uncertainty principle?
  
• Are our actions random? I mean we respond to something like let's say you did any task for no reason so like lifted a chair.
  
• I saw that dimensional formula of "distance covered in #n^(th)" "# second is #[LT^-1]#". How is that possible when unit of distance is #[L]?#
  
• Is the atomic radii of nitrogen larger than oxygen or smaller?
