FAQs on Quick Revision: Electromagnetic Waves - Physics for EmSAT Achieve

1. What are electromagnetic waves?
Ans. Electromagnetic waves are a form of energy that consists of both electric and magnetic fields oscillating at right angles to each other. They are produced by the acceleration of charged particles and can travel through a vacuum or a medium.
2. How are electromagnetic waves generated?
Ans. Electromagnetic waves are generated by the acceleration of charged particles. This acceleration can occur through various means such as the movement of electrons in an antenna, the vibrations of atoms and molecules, or the transitions between energy levels in atoms.
3. What are the different types of electromagnetic waves?
Ans. There are various types of electromagnetic waves, each with different wavelengths and frequencies. The electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
4. How do electromagnetic waves interact with matter?
Ans. Electromagnetic waves can interact with matter in different ways depending on their frequency. Lower frequency waves, such as radio waves, can pass through materials like walls and buildings. Higher frequency waves, such as X-rays and gamma rays, can penetrate matter but may be absorbed or scattered, causing ionization and damage to cells.
5. What are the practical applications of electromagnetic waves?
Ans. Electromagnetic waves have numerous practical applications in our daily lives. Some examples include radio and television broadcasting, wireless communication, radar systems, medical imaging technologies like MRI and X-rays, heating and cooking through microwaves, and optical technologies such as fiber optics and lasers.
