Consider two diffraction gratings with the same slit separation. The only difference between the two gratings is that one gratin
kobusy [5.1K]

Answer:

True The grid with more slits gives more angle separation increases

True. The grating with 10 slits produces better-defined (narrower) peaks

Explanation:

Such a system can be seen as a diffraction network in this case with different number of lines per unit length, the expression for the constructive interference of a diffraction network is

      d sin θ = m λ

where d is the distance between slits or lines, m the order of diffraction and λ the wavelength.

For network with 5 slits

      d = 1/5 = 0.2

For the network with 10 slits

      d = 1/10 = 0.1

let's calculate the separation (teat) for each one

      θ = sin⁻¹ (m λ / d)

for 5 slits

     θ₅ = sin⁻¹ (m λ 5)

for 10 slits

     θ₁₀ = sin⁻¹ (m λ 10)

we can appreciate that for more slits the angle increases

the intensity of a series of slits is

       I = I₀ sin²2 (N d/2) / sin² d/2)

when there are more slits (N) the peaks have greater intensity and are more acute (half width decreases)

let's analyze the claims

False

True The grid with more slits gives more angle separation increases

False

True The expression for the intensity of the diffraction peaks the intensity of the peaks increases with the number of slits as well as their spectral width decreases

False

Where are the nonmetals located on the periodic table? only in the first column in between the metalloids and the metals on the
BabaBlast [244]

<u>Answer:</u> The correct answer is on the far right side.

<u>Explanation:</u>

There are 3 main elements present in the periodic table:

Metals are the elements which have the tendency to loose electrons. they are located in the far left side of the periodic table.

Metalloids are the elements which shows both the properties of metals and non-metals. They are located in between metals and non-metals.

Non-metals are the elements present in the periodic table that have a tendency to gain electrons to attain stable electronic configurations. They are present in the far right side of the periodic table.

Hence, the correct answer is on the far right side.

Answer please just 1-7 it should be easy

1. As of right now, our solar system only includes asteroids and they are found in Kuiper Belt next to Saturn.

On May 6, 2020, scientists have discovered a mysterious blanket of darkness approximately 1,000 light years away from our solar system. However, in this case, black holes would not be a correct answer.

Even though constellations may seem close, they are actually far away since the size of the stars are immense and can be visible from light years away.  Constellations are not in our solar system.

Galaxies are groups of solar systems so therefore galaxies is not an answer.

2. Ptolemy was the man who proposed the early Earth-centered model of the universe and his model was called the Ptolemaic model also known as the geocentric model.

3. The planet that is most similar to Earth in mass and diameter is Venus.

4. The inner planets in our solar system are formed from dense elements and that is why they are able to withstand the intense of the sun. Meanwhile the outer planets were formed from gaseous materials but Pluto is so cold that its elements are hardened and dense.

5. The answer would be D since they orbit in the same direction and on the same plane.

6.  The speed of rotation determines the length and duration of day on a planet.

7.  The answer would be D since they have to have their own gravity, have a path clear of smaller bodies , and  orbit a star,
