Which of the following has minimum wavelength?
gamma rays
Which of the following has maximum de Broglie wavelength?
Electron has the least mass, so its wavelength is maximum.
Which has the largest de Broglie wavelength for the same speed?
Of the following, the one which has the largest de-Broglie wavlength for the same speed is. So, electron is the lightest particle of these four. So, λe is maximum.
Which of the following has the smallest de Broglie wavelength given that all have equal velocity?
Since the α-particle has the highest mass among the given entities, it has the smallest de-Broglie wavelength.
What is the shortest de Broglie wavelength?
alpha particle
Do electrons have fixed wavelength?
The wavelength of an electron wave Answer: (a) Has a fixed value. (a) We can make electrons have a wavelength that is much shorter than the wavelength of visible light. (b) We can make electrons have a wavelength that is much longer than the wavelength of visible light.
Why does the uncertainty principle make it impossible to predict a trajectory for the electron?
Why does the uncertainty principle make it impossible to predict a trajectory for the electron? Because the up says that you cannot know both the position and velocity of the electron simultaneously, you cannot predict the trajectory.
Why is Heisenberg’s uncertainty principle true?
The Heisenberg Uncertainty Principle states that it is impossible to determine simultaneously both the position and the velocity of a particle. The detection of an electron, for example, would be made by way of its interaction with photons of light. This reflected photon causes a change in the path of the electron.
Why don’t we observe such properties at the ballpark?
We don’t observe such properties at the ballpark because the mass of the ball is so large, its de Broglie’s wavelength is minuscule. here, λ is the wavelength, m is the mass, v is the velocity, h is the plancks constant. Now, from this relation, we see that the wavelength is inversely proportional to the mass.
What are complementary properties?
Complementary properties are those properties that exclude one another, i.e., the more you know about one, the less you know about the other. For example, the wave nature and particle nature of the electron are complementary. Heisenberg solved the paradox of how a particle can be both a particle and a wave.
What is Bohr’s complementarity principle?
Complementarity principle, in physics, tenet that a complete knowledge of phenomena on atomic dimensions requires a description of both wave and particle properties. The principle was announced in 1928 by the Danish physicist Niels Bohr. It is impossible to observe both the wave and particle aspects simultaneously.
What is complementary?
: completing something else or making it better : serving as a complement. —used of two things when each adds something to the other or helps to make the other better. : going together well : working well together.
What are complementary properties of an electron?
Answer: The complementary properties can be defined as those properties which cannot be simultaneously measured and observed; one can be measured or observed at a time. The electron diffraction demonstrates that the wave nature and the particle nature of the electron cannot be observed simultaneously.
What is the principle of complementarity quizlet?
Principle of Complementarity of Structure and function: -For example bones can support and protect body organs because they contain hard mineral deposits. Chemical Level: -At this level atoms, tiny building blocks of matter, combine to form molecules such as water and proteins.
What are complementary quantities?
In physics, complementarity is a conceptual aspect of quantum mechanics that Niels Bohr regarded as an essential feature of the theory. The complementarity principle holds that objects have certain pairs of complementary properties which cannot all be observed or measured simultaneously.
What is complementarity in psychology?
Complementarity is a factor which affects attraction in romantic relationships. It is also referred to as ‘complementarity of needs’ and is the final stage of filter theory. It refers to how well two people fit together (complement one another) and meet each other’s needs.
What is Homogamy in psychology?
n. a marriage between partners from similar ethnic, racial, religious, educational, or socioeconomic backgrounds. Compare heterogamy. ADVERTISEMENT.
What is complementarity in therapy?
Complementarity denotes the fit among the behaviors and roles of individual members or subsystems of a family. The difference is not trivial; it accounts for the structural therapist’s preference for addressing spatial arrangements (literal and metaphorical) among family members, rather than sequences of behavior.
How important is complementarity for relationship success?
Complementarity means that partners are different in ways that enable them to fit or work together well. Research has shown that these kinds of complementarity increase satisfaction and lower conflict in both dating and marital relationships.
What is a parallel relationship?
A couple relationship may be a consensual or marital union or a living-apart-together (LAT) relationship. When someone simultaneously has a sexual relationship outside of the steady couple relationship, this is called a parallel relationship.
