Homework Statement
a)Yellow light Lambda= 589nm falls on a double slit. The distance between two slits is d=0.5 mm the width of each slit is a=100 micrometer. A screen showing the interference pattern is located 4 m behind the slits.

ok let's check it
fn = n v/2L ---A
fn+1 = (n+1) v/2L ----B
fn = 466.2 Hz , fn+1 = 582.7 Hz
Therefore A becomes
466.2 = n (343 / 2L )
2.718L = n ------(i)
and B becomes by fn+1
582.7L = 171.5 n + 171.5 ---(ii)
putting n from i
L = 1.471 meter
and n is approx = 4...
f_n = n\frac{v}{2L}
I am applying it like
n = (fn * 2 L) / v but
n1=2.718 L
n2=3.397 L
n3=4.076 Lstill confusion how to find L to proceed finally for the harmonics ?

a)How long is each pipe?
b) Determine the first three harmonics of each pipe.
c) There is an organ pipe open at both...
Ohh Sorry ..
Now i got it ,
Tm4 = (T24 + T14)/2
Tm = 334.21 Kelvin
How does the radiation balance of P2 change with the insertion of PM?
What i m getting is radiation balance of P2 with P1 will change after the insertion but how can we define it ?
Thanks a lot for the help ,
sA(TM4 - T14) = sA (T24 - TM4) By canceling sA
(TM4 - T14) = (T24 - TM4)
Tm4 = (T24 - T14)/2
Tm4 = 6.9106 10^9 .
How does the radiation balance of P2 change with the insertion of PM?
Thanks again
Ok, Thanks a lot for the hint . I tried it please take a look at it ...
According to Stefans LAW
P=SAT^(4) P = Power radiated in W (J/s)
