Answer:
0.00001266 m
Explanation:
D = Distance from source to screen
m = Order
d = Slit separation
The distance from a point on the screen to the center line
At m = 0
At m = 1
The slit separation is 0.00001266 m
<span>There are several main pieces of evidence that support the Big Bang theory.
One is the fact that the universe is expanding, proven with something
called red shift. The second is something called cosmic microwave
background radiation. The third is the abundance of different elements
in the universe.

Answer:
the correct one is the third :
can travel through a region void of matter and mechanical waves cannot
Explanation:
Mechanical waves travel supported by a material medium, for example sound waves travel in air, the wave on a string travels on the string.
Electromagnetic waves are produced by the variation of electric and magnetic fields, after producing this variation by the lenz law the variation of one field induces the other, so these waves do not need a material medium to travel.
Of the final statements the correct one is the third :
can travel through a region void of matter and mechanical waves cannot
