Answer:
d = 68.5 x 10⁻⁶ m = 68.5 μm
Explanation:
The complete question is as follows:
An optical engineer needs to ensure that the bright fringes from a double-slit are 15.7 mm apart on a detector that is 1.70m from the slits. If the slits are illuminated with coherent light of wavelength 633 nm, how far apart should the slits be?
The answer can be given by using the formula derived from Young's Double Slit Experiment:
where,
d = slit separation = ?
λ = wavelength = 633 nm = 6.33 x 10⁻⁷ m
L = distance from screen (detector) = 1.7 m
y = distance between bright fringes = 15.7 mm = 0.0157 m
Therefore,
<u>d = 68.5 x 10⁻⁶ m = 68.5 μm</u>
The answer is always true a
Yes, a test could be performed to support the claim.
Hypothesis: The claim that a manufacturer’s cleanser works
twice as fast as any other cleanser.
So, based from this hypothesis, we can perform the following
tests:
We assign Cleanser A to the manufacturer that claims that their cleanser works
twice as fast as any other cleanser and Cleanser B to the cleanser to be
compared with.
1.
Get two tiles and put the same amount of stain
on them.
2.
Apply Cleanser A on the first tile and Cleanser
B on the second tile.
3.
Apply the same amount of force in removing the
stains on both tiles
4.
Record the amount of time it takes to remove the
stains on each tile.
Answer:
Today, scientists believe that the main reason the earth has had periodic ages is that the climate of earth is controlled by the difference in heating of it's surface by the sun. As for example, the equatorial regions are the warmest as the sun is vertically overhead of those areas and the polar regions where the sun is at the extreme angels are the coldest ones.
Explanation:
Answer: Density--> the amount of mass in a given volume
Boiling point: the tempeture when a liquid becomes gas
Conductivity: the ability of a subtance to transfer heat or electricety
Bouyant force: The upward force of an object in a liquid
soulibility: the ability of a subtance to disolve in other.
