Q. The work function of a metal surface is 1.8 eV. Compute the threshold wavelength.
Work function W = hγo = h C / λ 0
λ 0 = h C / W
= 6.626 X 10-34 X 3 X 10 8 / 1.8 X 1.6 X 10 -19
= (19.878 / 2.88) X 10-7 m
= 6.902 X 10-7 m
what to right
If the thickness of the slab is increased what happens to lateral shift?
mass=volume * density.By using this formula we can find the mass of sphere. Volume of sphere=(4/3)pi*r^3 V=(4/3)*3.14*(1*10^-2)^3=4.187*10^-6 Mass=(4.187*10^-6)*900=3768*10^-6kg
which type of diode we have use ?
Do fibers have losses? Everything in the universe is inefficient. It means that while a measured amount of something enters in a system, less comes out than initially went in.
