10 Questions
What does engineering physics or engineering science refer to?
Engineering physics or engineering science refers to the study of the combined disciplines of physics, mathematics, chemistry, biology, and engineering, particularly computer, nuclear, electrical, electronic, aerospace, materials or mechanical engineering.
How does engineering science differ from traditional engineering disciplines?
Engineering science/physics is not necessarily confined to a particular branch of science, engineering or physics, but is meant to provide a more thorough grounding in applied physics for a selected specialty.
What are some examples of specialties within engineering science/physics?
Specialties within engineering science/physics include optics, quantum physics, materials science, applied mechanics, electronics, nanotechnology, microfabrication, microelectronics, computing, photonics, mechanical engineering, electrical engineering, nuclear engineering, biophysics, control theory, aerodynamics, energy, and solid-state physics.
What is the focus of engineering science/physics?
It focuses on the scientific method as a rigorous basis, seeking ways to apply, design, and develop new solutions in engineering, and it is devoted to creating and optimizing engineering solutions through enhanced understanding and integrated application of mathematical, scientific, statistical, and engineering principles.
How does engineering science/physics bridge the gap between theoretical science and practical engineering?
It is meant for cross-functionality and bridges the gap between theoretical science and practical engineering with emphasis in research and development, design, and analysis.
Who discovered the Compton effect and in what year?
Arthur Holly Compton discovered the Compton effect in 1923.
What is the Compton effect and how does it deviate from classical theories?
The Compton effect is the interaction between high frequency photons and charged particles, leading to a decrease in energy and an increase in wavelength of the photon. It deviates from classical theories by using special relativity and quantum mechanics to explain the interaction.
What are the two ways in which photons can interact with matter at the atomic level?
Photons can interact with matter at the atomic level through the photoelectric effect and Rayleigh scattering.
What is the implication of the conservation of energy in the Compton effect?
The implication of the conservation of energy in the Compton effect is that the lost energy from the photon is transferred to the recoiling particle, resulting in a decrease in energy of the photon and an increase in energy of the recoiling particle.
What is Inverse Compton Scattering and when does it occur?
Inverse Compton Scattering is when the scattered photon increases in energy. It occurs when the recoiling particle initially carries more energy than the photon.
Study Notes

Specialties within Engineering Science/Physics
- Examples include quantum mechanics, relativity, statistical mechanics, and electromagnetic theory
- Also includes materials science, nanotechnology, and biophysics
Focus of Engineering Science/Physics
- Focuses on understanding the underlying physical principles that govern the behavior of systems and devices
- Aims to develop new technologies and solutions by applying these principles
Bridging the Gap between Theory and Practice
- Engineering science/physics bridges the gap between theoretical science and practical engineering by applying theoretical principles to real-world problems
- Provides a fundamental understanding of the underlying physics, enabling the development of innovative solutions
Compton Effect
- Discovered by Arthur Compton in 1923
- Refers to the phenomenon where the wavelength of light increases after it scatters off free electrons
- Deviates from classical theories, which predict that the wavelength of light remains unchanged
Photon-Matter Interactions
- Photons can interact with matter at the atomic level through two ways: scattering and absorption
- Scattering involves the deflection of photons, while absorption involves the transfer of energy from photons to atoms
Conservation of Energy
- The conservation of energy implies that the energy lost by the photon is gained by the electron
- This principle is fundamental to the Compton effect, as it explains the energy transfer between photons and electrons
Inverse Compton Scattering
- Occurs when a low-energy photon scatters off a high-energy electron, resulting in a increase in the photon's energy
- The inverse of the Compton effect, where the photon's energy is increased rather than decreased
