Is there any wave functio in quantum mechanics in 2d where there is no mass term?

Asin(2*pi*x/lambda + d) is the general wavefunction of a standing wave, and includes no mass term.
(Were A = amplitude, pi = 3.14159265358979323646, x = position, lambda = wavelength and d = phase at x=0).

What you need to study the quantum mechanics?
Quantum mechanics studies the movement and interaction of subatomic particles, like electrons, nucleons, quarks, etc.
What is the Difference between relativity and quantum mechanics?
Quantum Mechanics is the study of the intimate behavior of the smallest forms of particles, and their interaction amongst, with special emphasys on the emissions of energy, which is delivered in quanta, or photons. Wave Mechanics is the study of many physical phenomena that happen in a non linear and recurrent behavior, usually addressed as wave, with special emphasys in both the features of said wave, and the energy that involves specific wave phenomena.
Can two photons interact with an electron simultaneously?
Yes. This effect is called "two-photon absorption" or "two-photon stimulated emission" and is described by the second order term in quantum-mechanics perturbation theory.
What is planks quantum hypothesis?
That light comes in indivisible chunks (he called them "quanta" but the present term is "photons") and that the energy of each such quanta is equal to the frequency of that light times a constant (now called Planck's Constant). When Max Planck first proposed this idea in 1900, he only noted it as a mathematical curiosity that would permit a solution to the spectrum of black-body radiation. In other words, he didn't assert that it was actual description of reality. In 1905, Einstein noted that this same assumption would fully explain the photoelectric effect.
Who is Bohr?
One of the physicists that worked on Quantum Mechanics in the 1920s and 1930s. He is Danish and lived in Copenhagen. He is most popularly known for his interpretation of Quantum Mechanics that came to be called the Copenhagen Interpretation (which Einstein strongly opposed).During WW2 following the Nazi invasion of Denmark, he nearly died in a unpressurized part of a British bomber from lack of oxygen, even though he was given an oxygen mask and bottle, when the mask came loose from his large head and he blacked out before he could put it back.
Is quantum mechanics a set of fields or is it just a lone branch of mechanics?
Quantum mechanics is a separate branch of physics. It is a general term given to all quantum physics. There are many subbranches, for example Quantum chronodynamics which describes the strong nuclear interaction.
What is a bidoublet?
A bidoublet is a term used in quantum mechanics for a binary doublet.

From the definition of quantum mechanics what does mechanics imply?
Mechanics is not a physics term in the first place, but a logic term. It means "natural link of cause and consequence". When something happens, it has consequences, and the sum of both a cause and its consequence is known as a mechanical phenomenon. So, the knowledge or study of the intimate behavior of something is known as the "mechanics" of said something. Quantum Mechanics is the branch of Physics that studies the intimate behavior of the particles and phenomenons of quantic scale.
What is the definition of classical physics?
Classical physics is the physics without considering quantum mechanics. This is the type of physics practiced by for example Newton (you might also come across the term Newtonian physics). General relativity is also a classical theory. The distinction is often used because quantum mechanics changed quite a bit in many fields of physics, so the term 'classical physics' allows for a clear distinction. The opposite of classical physics would be quantum physics.
What does it mean in quantum mechanics to say something is objectively real?
In quantum mechanics, it is often necessary to separate how things appear and how things are/could be. For example, when I stand on the floor, it appears to be solid without any breaks, but on a quantum scale, it is mostly empty space. In this example, my subjective opinion of the floor differs from the objective quantum reality of the floor. What we call "reality" behaves in different ways depending on the perspective. The objectively real or objective reality is a term to describe the way things are, not how they seem.

What does the term quantum of energy mean?
Specific quantity of energy

What is the term used to label the energy level of electron?
Principal quantum numbers (n).
