Consider a free particle of mass m, moving in one dimension in the positive x direction, in a quantum energy eigenstate in the lab frame. in this lab frame, the coordinate and time labels are denoted by x and t respectively, and the wavefunction, y (x, t), has wavelength 2. now consider the same quantum state observed from a reference frame moving with velocity v, where the coordinates, (x', t'), are related to the lab frame coordinates by the galilean transformation: x= x - vt and t=t. the wavefunction of the particle, as observed from the moving frame, is ý (x',t'). (a) using de broglie's formula or otherwise, find the relation between the wavelength, a', of the particle in the moving frame, and the wavelength, a, in the lab frame. (b) the wavefunctions y (x, t) and ý (x',t') satisfy the schrodinger equation written down in the lab and moving reference frames, respectively. using the ansatz w(x, t)= * (x – vt, t) where a and b are constants to be determined, find the values of a and b, using the schrodinger equations in the two reference frames.

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.
