<h2>
Answer</h2>
The physical state of the elements depends upon the <u>attraction forces </u>and their <u>kinetic energy</u>.
<h2>
Explanation</h2>
The elements or substances are fixed with each other with the help of different chemical forces including ionic bonding, covalent bonding, H- bonding etc. The strength of these forces is also one of the factors that affect their physical natures. For example, covalent or ionic bonds are the strongest bonds than all other bonds and metals that contain these forces are mostly in solid form. The kinetic motion of electrons in the element also affects the physical state of the element and potential of bonding.
With the use of the formula SinФ = nλ / d, there are 16 spectral orders which can be seen when it is illuminated by white light.
Given that a grating has 2000 slits/cm. That is,
d = 0.01 / 2000
d = 5 x
m
The wavelength λ = (700 - 400) nm
λ = 300 x
m
To calculate how many full spectral orders that can be seen (400 to 700 nm) when it is illuminated by white light, we will use the below formula
SinФ = nλ / d
Φ =
(nλ / d)
When n = 1
Φ =
(300 x
/ 5 x
)
Φ = 3.4 degrees
when n = 2
Φ =
(2 x 300 x
/ 5 x
)
Ф = 6.9 degrees
When n = 3
Ф =
(3 x 300 x
/ 5 x
)
When n = 16
Ф =
(16 x 300 x
/ 5 x
)
Ф =
(0.96)
Ф = 73.7 degrees
when n = 17
Ф =
(17 x 300 x
/ 5 x
)
Ф =
(1.05)
Ф = Error ( that is, it does not exist)
Therefore, there are 16 spectral orders which can be seen when it is illuminated by white light.
