Answer:
y and length is directly relation
Explanation:
Given data
A single-slit diffraction pattern is formed on a distant scree
angles involved = small
to find out
what factor will the width of the central bright spot on the screen change
solution
we know that for single slit screen formula is
mass ƛ /area = sin θ and y/L = sinθ
so we can say mass ƛ /area = y/L
and y = mass length ƛ / area .................1
in equation 1 here we can see y and length is directly relation so we can say from equation 1 that the width of the central bright spot on the screen change if the distance from the slit to the screen is doubled
Answer:
The precision at which the number was measured
Explanation:
The number of digits that you use to record a measurement indicates the precision of the measurement.
<h2>
Answer: Diamond</h2>
Explanation:
This described situation is known as Refraction, a phenomenon in which the light bends or changes it direction when passing through a medium with a index of refraction different from the other medium.
In this context, the index of refraction is a number that describes how fast light propagates through a medium or material.
According to Snell’s Law:
(1)
Where:
is the first medium index of refraction (air)
is the second medium index of refraction (the value we want to know)
is the angle of the incident ray
is the angle of the refracted ray
Now, let's find from (1):
(2)
Substituting the known values:
Finally:
If we compare this result with the given table, the index of refraction value that is close to this number is diamond's index of refraction.
Therefore, the correct option is A: the material is diamond.
Answer:
The carpet has a buildup of electrons in it that get released onto your body when you rub across the floor while the hardwood doesn't have electrons built up inside of it.
