Answer:
a) 0.063m
b) 2.72°
c) 3151 fringes
d) 1.87*10^-6m
Explanation:
a) To find the screen distance you use the following formula:
D: screen distance
d: distance between slits
m: order of the fringes
λ: wavelength
By replacing the values of the parameters you obtain:
b) The condition for dark fringes is given by:
for the first dark fringe the angle is:
c) the visible number of fringes is given by:
d) the wavelength of a laser in which its first order fringe coincides with the third one of the CuAr laser is:
Answer:
wouldn't they be dead and there's no oxygen in space....right???
Answer:
Explanation:
Un electrón tiene una carga negativa de 
y la masa total es igual al producto del número de electrones y esa carga unitaria. El número de electrones se obtiene al dividir la carga total por la carga unitaria. (An electron has a negative charge of and the total mass is equal to the product of the qunatity of electrons and such unit charge. The quantity of electrons is found by diving the total charge by the unit charge):
It’s a vector quantity, which means it possesses both magnitude and direction. So the SI unit would be B)kg•m/s
