Answer:
λ = 864 nm
Explanation:
To find the wavelength of the light you use the following formula, which determines the position of the m-th fringe in an interference pattern:
(1)
ym: position of a bright fringe
D: distance from the slits to the screen = 3,7 m
d: distance between slits = 0,2mm = 0,2 *10^-3 m
m: order of the fringe
λ: wavelength of the light
You have the distance from the central peak to the third fringe (0,048m). Then, you can use the equation (1) with m=3 and solve for the wavelength:
henc, the wavelength of the light is 864nm
The reason why there is a difference between free-fall acceleration is a centrifugal force.
I attached a diagram that shows how this force aligns with the force of gravity.
From the diagram we can see that:
Where g' is the free-fall acceleration when there is no centrifugal force, r is the radius of the planet, and w is angular frequency of planet's rotation.
is the latitude.
We can calculate g' and wr^2 from the given conditions in the problem.
Our final equation is:
Colatitude is:
