Answer:
The correct answer is "4.26 m".
Explanation:
Given:
Wavelength,
or,
Distance,
or,
Distance between the 1st and 2nd dark fringes,
As we know,
⇒
or,
⇒
By substituting the values, we get
Answer:
spacing is 0.8307 mm
Explanation:
given data
wavelength = 500 nm
interference fringes N = 1.5 mm
wavelength = 640 nm
to find out
spacing between the fringes
solution
we know bright fringe spacing in double slit is express as
w × sinθ = N × wavelength
so angle is
sinθ = N × wavelength / w
and spacing is express as
spacing = d sinθ
and that is = N × (d/w) × wavelength
so
spacing = 1.5 × 360 / 650
so spacing is 0.8307 mm

Explanation:
An object is in motion if its position changes relative to another object. To decide if you are moving, you can use your chair as a reference point. A reference point is a place or object used for comparison to determine if something is in motion.
Explanation :
Corrosion is the process of conversion of metal into its oxides, hydroxides and sulfides.
Rusting of iron is the process of corrosion in metals. Iron objects react with oxygen in the air and turned reddish. This reddish covering is Rust.
where, is iron
is oxygen present in atmosphere
and is rust or Ferric oxide.
In the given equation, and both are reactants and is a product.
Answer:
6 rad/s
Explanation:
In a spring the angular frequency is calculated as follows:
where is the angular frequency, is the mass of the object in this case , and is the constant of the spring.
To calculate the angular frequency, first we need to find the constant which is calculated as follows:
Where is the force: , and is the distance from the equilibrium position: .
Thus the spring constant:
And now we do have everything necessary to calculate the angular frequency:
the angular frequency of the oscillation is 6 rad/s
