FAQs on Practise Question - 20 Video Lecture - Crash Course for EmSAT Achieve

1. What is the average speed of an electron in X-ray?
Ans. The average speed of an electron in X-ray can vary depending on the energy of the X-ray. Generally, electrons in X-ray have speeds ranging from a few thousand kilometers per second to a fraction of the speed of light.
2. What factors affect the speed of electrons in X-ray?
Ans. The speed of electrons in X-ray can be affected by several factors, including the energy of the X-ray, the electric field strength, and the presence of any external magnetic fields. Additionally, the mass and charge of the electron also play a role in determining its speed.
3. How is the average speed of an electron in X-ray related to its energy?
Ans. The average speed of an electron in X-ray is directly related to its energy. As the energy of the X-ray increases, the speed of the electron also increases. This relationship follows the principles of conservation of energy, where the increase in energy is converted into an increase in the kinetic energy and speed of the electron.
4. Can the average speed of an electron in X-ray exceed the speed of light?
Ans. No, the average speed of an electron in X-ray cannot exceed the speed of light. According to the theory of relativity, the speed of light is the ultimate speed limit in the universe. Electrons, being particles with mass, are bound by this limit and cannot surpass it.
5. How is the average speed of an electron in X-ray measured?
Ans. The average speed of an electron in X-ray can be measured using various experimental techniques. One common method is to observe the electron's deflection in an electric or magnetic field and calculate its speed based on the applied forces and the resulting trajectory. Other techniques involve analyzing the energy and wavelength of the X-ray to indirectly determine the electron's speed.
