the wavelength goes down if the velocity of the wave is constant
at the end of this little scenario, ivana is 1 km south of where she started.
answer : lower than the mercury in the vessel, and shaped like the outside of an umbrella.
explanation : we know that the capillary action, in this the inter-molecular force within the mercury exceed those between the glass and the mercury
hence, a convex meniscus form and capillary action work in reverse.
so, if a small diameter open glass tube is partially immersed in a vessel containing mercury, the surface of the mercury inside the tube will be lower than the mercury in the vessel, and shaped like the outside of an umbrella.
