## FAQs on Mindmap: Electromagnetic Waves - Physics Class 12 - NEET

 1. What are electromagnetic waves?
Ans. Electromagnetic waves are a form of energy that is produced by the acceleration of electric charges. They consist of electric and magnetic fields that oscillate perpendicular to each other and travel through space at the speed of light.
 2. How are electromagnetic waves generated?
Ans. Electromagnetic waves are generated when an electric charge is accelerated or decelerated. This acceleration creates a changing electric field, which in turn generates a changing magnetic field. These changing electric and magnetic fields then propagate through space as electromagnetic waves.
 3. What are the properties of electromagnetic waves?
Ans. Electromagnetic waves have several key properties. They can travel through a vacuum, they travel at the speed of light, they have both electric and magnetic components, they can be reflected, refracted, and diffracted, and they can be polarized.
 4. How are electromagnetic waves classified?
Ans. Electromagnetic waves are classified based on their wavelengths and frequencies. The electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
 5. What are some practical applications of electromagnetic waves?
Ans. Electromagnetic waves have numerous practical applications in various fields. They are used for communication through radio waves, microwaves, and visible light. They are also used in medical imaging technologies such as X-rays and MRI scans. Additionally, electromagnetic waves are utilized in remote sensing, wireless technologies, and energy transmission.
