Answer:
For differents τ:
τ = 1000 Å → B = 0.11°
τ = 750 Å → B = 0.15°
τ = 250 Å → B = 0.44°
For differents Θ:
Θ = 10° → B = 0.31°
Θ = 45° → B = 0.44°
Θ = 80° → B = 1.78°
Explanation:
To factor B is related to the size of particles, Θ, and λ by the Scherrer equation:
<em>where τ: size of the particles, λ: is the wavelenght of the X-Rays, B: is the line broadening at half the maximum intensity, Θ: angle of incidence and K: is a shape factor with typical value of 0.9 </em>
Now, factor B for the diameter of the particles (τ) is:
τ = 1000 Å:
τ = 750 Å:
τ = 250 Å:
For τ = 250 Å, factor B for angles of incidence is:
Θ = 10°:
Θ = 45°:
B = 0.438°
Θ = 80°:
Have a nice day!

What type of change occurs when water changes from solid to a liquid a phase change a physical change and irreversible change both A and the
Answer and Explanation:
The light that comes from the sun is called white light. Actually white light is a mixture of lights of different colors. When we look at the rainbow we can see the colors that make up the white light. This phenomenon, known as dispersion, occurs when a ray of composite light is refracted (refraction) in some medium, and its constituent colors are separated.
I attached you I picture where you can see this process
Basically, when the light passes through a glass prism, the different wavelengths that make up the beam of light travel inside it at different speeds and curl differently when entering and leaving resulting in a beam deviated from the initial direction and with its separate components.
The correct answer to this question is this one:
By definition, if a molecule is composed of two hydrogen atoms and one oxygen atom, that molecule is a water.<span> In fact, the structure of water is written as H20, which signifies that two hydrogen (H) atoms and one oxygen (O) atom make up the molecule.</span>
