What are the two main theories covered by Quantum Physics?

Quantum field theory and quantum mechanics.

What does Quantum Physics study in terms of particle behavior?

Quantum Physics studies how particles behave at levels below the atomic.

How does Quantum Physics allow for realistic calculations within the microscopic arena?

At levels below the atomic, Quantum Physics allows for realistic calculations within the microscopic arena.

Why do happenings in the physical world sometimes appear strange when derived from calculations under quantum physics?

Derivations from calculations under quantum physics can sometimes appear strange when juxtaposed against workings within the physical arena because the microscopic arena is not discernible under ordinary circumstances.

Albert Einstein won the Nobel Prize for physics in 1921, but physically received it in 1922.

What breakthrough did Albert Einstein make in theoretical physics?

Albert Einstein made a breakthrough in theoretical physics, mainly on how the photoelectric effect occurs.

What principle did Albert Einstein come up with that led to the establishment of the law of photoelectric effect?

Albert Einstein came up with a principle that culminated in the establishment of the law of photoelectric effect.

What do physicists rely on to comprehend the behavior of light, as a result of Albert Einstein's work?

Physicists now rely on the law of photoelectric effect to comprehend the behavior of light.

  1. What is the significance of understanding the minutest details of light in daily operations?

Understanding the minutest details of light is important for both scholarly work and real-life applications.

  1. What are the theories studied within the field of quantum physics?

Quantum physics and quantum mechanics are the theories studied within the field of quantum physics.

  1. Why are equations in classical mechanics not practically applicable for describing motion and speed of electrons and atoms at the micro level?

Equations in classical mechanics are not practically applicable for describing motion and speed of electrons and atoms at the micro level because they do not account for quantum behavior.

  1. What does quantum mechanics explain?

Quantum mechanics explains how particles behave at sub-atomic levels and the reasons for such behavior.

  1. What does quantum mechanics deal with?

Quantum mechanics deals with the principles explaining the characteristics of matter and energy.

  1. Define the term 'quantum'.

The term 'quantum' describes the quantized nature of energy and matter, forming them into discrete quanta.

  1. Who initiated the study of quantum physics and when?

Quantum physics started with Max Planck's work on energy discreteness in 1900, which earned him the 1918 Nobel Prize.

  1. What is relevant in quantum physics concerning matter absorbing all light frequencies?

Blackbody radiation, involving matter absorbing all light frequencies, is relevant in quantum physics.

  1. How are photons, particles involved in light transmission, calculated?

Photons, particles involved in light transmission, are calculated using the Planck Equation: $E = hv = \frac{hc}{\lambda}$.

  1. What assumption did Planck make about the energy of electrons in oscillation?

Planck's assumption that electron's energy in oscillation has a minimum energy level led to the concept of energy quantization.

  1. How did Albert Einstein extend Planck's concept?

Albert Einstein extended Planck's concept, explaining that radiation can quantize into photons, leading to the photoelectric effect explanation.

  1. Whose work did Albert Einstein build upon when explaining the photoelectric effect?

Einstein's explanation of the photoelectric effect built on the work of physicists Heinrich Hertz and Wilhelm Hallwach in 1887.

Explain the concept of quantized nature of energy and matter in quantum physics and quantum mechanics.

The term 'quantum' describes the quantized nature of energy and matter, forming them into discrete quanta. This means that energy and matter can only exist in specific discrete amounts, or quanta, rather than in a continuous manner.

What is the Planck Equation and how is it used in quantum physics?

The Planck Equation is given by $E = hv = \frac{hc}{\lambda}$, where $E$ represents energy, $h$ is Planck's constant, $v$ is frequency, $c$ is the speed of light, and $\lambda$ is the wavelength. This equation is used to calculate the energy of photons, the particles involved in light transmission.

Who was awarded the Nobel Prize for his work on energy discreteness, and in which year?

Max Planck was awarded the Nobel Prize in 1918 for his work on energy discreteness, which marked the beginning of quantum physics.

What is the significance of the photoelectric effect in the development of quantum physics?

The photoelectric effect, explained by Albert Einstein, demonstrated the quantization of radiation into photons and provided strong evidence for the particle-like behavior of light. This was a significant development in the understanding of quantum physics.

How did Albert Einstein's work extend and build upon Max Planck's concept of energy quantization?

Albert Einstein extended Planck's concept by explaining that radiation can quantize into photons, which further solidified the concept of energy quantization. This led to his explanation of the photoelectric effect, building on the work of previous physicists.

What does quantum mechanics explain and at what level does it operate?

Quantum mechanics explains how particles behave at sub-atomic levels and the reasons for such behavior. It operates at the microscopic level, dealing with the principles explaining the characteristics of matter and energy.

How are equations in classical mechanics different from those in quantum mechanics?

Equations in classical mechanics are not practically applicable for describing motion and speed of electrons and atoms at the micro level, while quantum mechanics provides the appropriate equations to describe such behavior.

Who initiated the study of quantum physics and with what work?

Quantum physics started with Max Planck's work on energy discreteness in 1900, which laid the foundation for the field and earned him the 1918 Nobel Prize.

What are the primary subjects of study within the field of quantum physics?

Quantum physics and quantum mechanics are the primary subjects studied within the field of quantum physics, with many terminologies relevant to both areas.

What did Planck's assumption about the energy of electron oscillation lead to?

Planck's assumption that electron's energy in oscillation has a minimum energy level led to the concept of energy quantization, which was a fundamental breakthrough in the development of quantum physics.

How did Einstein's explanation of the photoelectric effect contribute to the understanding of quantum physics?

Einstein's explanation of the photoelectric effect built on the work of physicists Heinrich Hertz and Wilhelm Hallwach in 1887, and it provided a crucial demonstration of the quantization of radiation into photons, further advancing the understanding of quantum physics.
