Answer:
λ = 1.388 x 10⁻⁶ m = 1388 nm
Explanation:
We can use the Young's Double Slit experiment formula here to solve this numerical:
where,
λ = wavelength = ?
Δx = distance between adjacent bright fringes = 1.62 cm = 0.0162 m
d = slit separation = 0.24 mm = 0.00024 m
L = distance from screen to slits = 2.8 m
Therefore,
<u>λ = 1.388 x 10⁻⁶ m = 1388 nm</u>
<span>when it returns to its original level after encountering air resistance, its kinetic energy is decreased.
In fact, part of the energy has been dissipated due to the air resistance.
The mechanical energy of the ball as it starts the motion is:
</span>
<span>where K is the kinetic energy, and where there is no potential energy since we use the initial height of the ball as reference level.
If there is no air resistance, this total energy is conserved, therefore when the ball returns to its original height, the kinetic energy will still be 100 J. However, because of the presence of the air resistance, the total mechanical energy is not conserved, and part of the total energy of the ball has been dissipated through the air. Therefore, when the ball returns to its original level, the kinetic energy will be less than 100 J.</span>
