Refraction of Light..Bond length
Bond length is the average distance between the centres of the nuclei of two bonded atoms in a molecule. It is expressed in Angstrom units () or picometers(pm). 1 = 10 - 1 0 m and 1pm = 10 - 1 2 m. It is determined with the help of X-rays diffraction and other spectroscopi..

from the above two equations we have Since all distances are measured from P CB = PB - PC CB l = PC - PB l Therefore, Using the sign convention, PB = - u (object distance) PC = -R PB = -v (Image distance) On substitution, +uR - uv = uv - vR uR + vR = 2uv Dividing both ..

i really understood it and this teachers left me amazed and opened my eyes to the real world of math! Thanks a lot ,i mean it - Alina
Tutor Vista perceived the math apps well and I enjoyed getting to work with Tutor Vista - Savannah
Better than great. That was the best 45 minutes i have spent on here. We got a lot done and i have a better understanding of the material. Thanks
I could not get time to help my daughter with her homework so I looked on net about online tutoring, we tried tutorvista for a week, my daughter liked it, so, now I got her join it.
