Answer:
Explanation:
There is reflection ( two times ) from upper and lower surface of the film . In both cases , reflection is from low to high density medium so there is change in phase of 180 twice .
So for constructive interference
2μd = n λ₁ , d is thickness required , λ is wavelength n₁ is order of bright fringe
For destructive interference ( minimum light )
2μd = (2n+1) λ₂/2
n λ₁ =(2n+1) λ₂/2
(2n+1) / 2n = λ₁ / λ₂
= 650 / 505
= 5 / 4 ( approx )
2n = 4
n = 2
2μd = n λ₁
2 x 1.33 x d = 2 x 650 nm
d = 488.72 nm
<span> delta S. The
change in entropy is a measure of how the reaction will affect the
system's stability. If delta S is negative, the system will become more
stable as it reacts, so it will be spontaneous. Delta H will follow
the same rule. </span>

IV - The miracle grow (since this does not change based on the dv)
DV- The height of the plant (since it depends on how much/ wether miracle grow was added.)
Control- The control would be the plant without any miracle grow
Hypothesis- If miracle grow is added to the plant, then it will grow taller because it will give the plants the nutrients it needs.
