13isn't it cauchy's equation???
μ=A+B/λ2
so..power is inversely proportional to λ2

1explanation .. 1/λ = R (1/ n12 - 1/n22)
here R is proportional to m (mass of e-)
so here the formula becomes :
1/λ = RX 3 (1/ n12 - 1/n22)
=> 1/λ = 3R (1/4 -1/9)
=> λ = 12/5R
hence ans is B and D (sorry for the prev post :()
1the next one ...
someone asked .... i think celestine....
chcek that discussion .. (there has been a long discussion..)
1ok next ques........a very easy self made CBSE ques.....plzz dont use google...hehe.
What are the constituents of GERMAN SILVER??
a. Brass+Zinc
b.Bronze+Tin
c.Brass+Nickel
d.Bronze+Nickel
e.German shepherd+ Silver
f. I think its (e)
1one more..............
Which of the following has the highest entropy???
a. one atom of H....
b. one molecule of CH3COOH
c. one ozone molecule
d. Akand
e. What is entropy??I dunno wat u r talkin about...
1hey sky..........i cudnt find tht celestine's thread........can u plzz explain???? or send tht link......
1well.. akand ... i din get the meaning of ur entropy question...
entropy ... cant be found out in that way...
i mean we can find the change in entropy for a particular process
like,,
u cant find out the potential of anything... u can just find the potential diff ...
so atleast i dun hav any answer for that question :(

chcek this...
1i dont think so sky............... entropy is d measure of randomness...
example.......which has more entropy....solid or gas??
gas..obviously
1In many branches of science, entropy is a measure of the disorder of a system. The concept of entropy is particularly notable as it is applied across physics, information theory and mathematics.
In thermodynamics (a branch of physics), entropy, symbolized by S,[3] is a measure of the unavailability of a system’s energy to do work.[4][5] It is a measure of the disorder of molecules in a system, and is central to the second law of thermodynamics and to the fundamental thermodynamic relation, both of which deal with physical processes and whether they occur unexpectedly. Spontaneous changes in isolated systems occur with an increase in entropy. Unexpected changes tend to average out differences in temperature, pressure, density, and chemical potential that may exist in a system, and entropy is thus a measure of how great the unexpected changes are.

1Sorry to ask this ques............but how do we derive F=qvB??? I cant find it any wher.... wel i think by dimensional formula hehe
1ok...........sum1 tel me how shud i show that a power of a lens is inversely proportional to λ2................???
wid steps plzzzz
1ya it is..............but shud we hav to kno it.........its too complicated.....
is it enuf to kno tht μ is inversely prop to λ2???? or shud v kno d whole formula??
1ok better.......i dint kno bout A and B...............those constants are too big.............by d way thnx..........
wat bout F=qvB wala???

ans d Akand....[9]
13a. one atom of H....
b. one molecule of CH3COOH
c. one ozone molecule
all r one in number...
so how ll they show randomness???
1prev to prev to prev ka ans :
we have quality factor Q=ω0L/R
ii) since quality factor of X > Y >Z
and ω0L is same for all .. so resistance used varies as z > y >x.
i) ω0C= 1/ω0L
ω0 and L are fixed.. so capacitance used in each case is same.
quality factor is highest for X. [see from the graph.. the one with highest peak has got high quality factor or more sharpness as well as high selectivity]
at ω0, the impedance is completely resistive since the circuit is in resonance.
