For Fraunhofer diffraction at a single slit would be represented by:
<span>a sinθ = mλ
</span><span>It should be noted that the angle needs be halved because we are only concerned with the angle between m=1 and m=0 and they gave you the angle between m=1 to the right of the center and m=1 on the left of the center. We calculate as follows:
</span>
<span>a sin(45/2)=(1)(470)
a = 1228 nm
Hope this answers the question. Have a nice day.

Answer:
1.76km
Explanation:
Here,
1mi = 1.6km
1.10 miles = 1.6 x 1.10 km
= 1.76 km
Using moving water to produce electricity is an example of changing one form of energy into another form of energy.
Answer:
Choices A, B, and C are correct.
Explanation:
Let us look at each of the choices one by one:
A. It is a vector
Yes. Velocity is a vector, or it's a speed with direction.
B. It is the change in displacement divided by the change in time.
Yes. The velocity can be written as
![v = \dfrac{\Delta\bold{x}}{\Delta t}](https://tex.z-dn.net/?f=v%20%3D%20%5Cdfrac%7B%5CDelta%5Cbold%7Bx%7D%7D%7B%5CDelta%20t%7D)
where
is the displacement—a vector quantity.
C. It can be measured in meters per second.
Yes. The units of velocity are m/s, but also with a unit vector indicating the direction.
D. It is the slope of the acceleration vs. time graph.
Nope. The velocity is the slope of displacement vs. time graph.
Hence, only choices A, B, and C are correct.
