Engg physics course wont fetch U fat pay cheques(atleast not after only BE). Its not that professional course. If U R interested in Physics+research in future(like MS/PhD), go for IITD.
If U want fat pay cheques, good BE branch and an assured safe future, go for BITS-Pilani CSE.
Although the scope for research(MS/PhD) is almost same in BITS-Pilani too. Both the colleges are reputed both in India as well as abroad.
So it now depends on ur field interest. If U R interested in comps, then BITS-Pilani. If U want to do research in physics, then IITD.
All the best for whatever decision U take. :)

I am getting 18.75 as the answer but its not there in the options. :(

Particle nature in ray optics.
Wave nature in wave optics.

Simply becoz IITs dont want rocket scientists for their UG programmes. 
U R taught ONLY basics for IITJEE. All these higher concepts are taught in higher studies.

Brilliant Tutorials provides the best correspondence course.

Depends upon U.
College- NSIT>NIT kurukshetra
Branch- ECE>ICE
So, if U R branch specific, go for NIT, if U R college specific, go for NSIT.

Phenoxide ion.
Due to -ve charge on O, it increases electron density at O/P positions more than phenol.

But how can U talk abt KE if U R considering the wave nature of light. I am a bit confused abt this.
But I am sure abt one thing that both the nature's of light viz., particle and wave are valid and we can define the KE thing here using the particle nature of light.
And E=h.nu is the TOTAL energy of light and not KE. Maybe it happens that total energy remains same but KE changes. I am not so sure with this thing considering the wave nature of light.

@mukulaish,
1 is also correct. Its given in many books including NCERT.

Sorry, I am not able to get ur doubt.
Contradiction to law of conservation of energy kahan se aa gaya?
When we talk abt particle nature of light, we say that light is made up of particles known as photons. Now particles can have K.E. When it enters in a medium, the interaction of these photons with the particles of medium changes.
For ex-in a denser medium, the photons experience more force opposing their movement. It maybe due to increased friction or more collisions of photons with more closely packed particles of dense medium. And due to this force, the K.E. of photons wud decrease in a denser medium.
Hope its clear now.

Use this formula-
Where, Veff=effective voltage
Vi=individual voltages
ri=internal resistances of batteries.
Hope it helps U.

If U consider light's particle nature, then YES.
Obviously the KE of photon wud change becoz the velocity of light is different in different mediums.

@krish1092,
Arre to maine kab kaha that alpha particles have empty space???? :O :O :O

R U sure that the question is correct?
There can be infinite equations of the perpendicular legs(consider the hypotenuse as the diameter of a circle, now there can be infinite points on the circle's circumference).
Correct me if I am wrong.
