Answer:
m = 4
Explanation:
The expression that explains the constructive interference of a diffraction pattern is
a sin θ = m λ
where a is the width of the slit and λ the wavelength
sin θ = m λ / a
The maximum value is for when the sine is 1, let's substitute
1 = m λ/a
m = a /λ
let's reduce the magnitudes to the SI system
a = 2.1 um = 2.1 10⁻⁶
lam = 475 nm = 475 10⁻⁹ m
let's calculate
m = 2.1 10⁻⁶ / 475 10⁻⁹
m = 4.42
with m must be an integer the highest value is
m = 4
Answer:
a. It creates a pattern of alternating rock stripes on both sides of a mid-ocean ridge.
Explanation:
Seafloor spreading is the theory that the oceanic lithospheric plates are in constant motion just as continental drift occurs.
When oceanic plates collide, the denser subducts under the less dense one, causing a destruction of oceanic lithosphere.
However, during seafloor spreading, a rift in the ocean can spill out some of the partially melted subducted rock. When the magma cools, there is an alternation in the magnetic variation of rocks formed by the series of volcanic action that has occurred underwater.
The variation shows younger rocks closer to the mid-oceanic ridge formed in the process. This variation is measured and compared to confirm that sea floor spreading has actually occurred.
Hey there!
Here is your answer:
<u><em>The proper answer to this question is a "igneous rock".</em></u>
Reason:
<u><em>Metamorphic rock: Formed by heat and pressure under the Earths crust.</em></u>
<u><em>Sedimentary rock: Formed by deposition in rivers and pressure causes the rocks to compact.</em></u>
<u><em>Igneous rock: The cooling of lava and it crystalizes.</em></u>
<em>Therefore the answer is Igneous rock.</em>
