FAQs on Electromagnetic Waves JEE Main Mock Test 2025-26: Practice & Excel
1. What are electromagnetic waves?
Electromagnetic waves are energy waves that travel through space at the speed of light, created by the movement of electric and magnetic fields. These waves do not require a medium to pass through and include types such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
2. What is the difference between magnetic and electromagnetic waves?
Magnetic waves refer to magnetic field variations alone, while electromagnetic waves involve oscillating electric and magnetic fields that travel together. Electromagnetic waves can move through a vacuum, whereas pure magnetic fields cannot travel without a medium.
3. Can you feel electromagnetic (EMF) waves?
Humans cannot directly feel electromagnetic waves like radio waves or microwaves under normal conditions, because these frequencies do not activate any of our senses. Only certain types, such as visible light (seen by our eyes) or infrared (felt as heat), are detectable by our bodies.
4. What are the common symptoms of exposure to electromagnetic waves?
Most exposure to everyday electromagnetic waves is considered safe. Direct symptoms are not felt at low levels. However, extremely high doses (like X-rays or gamma rays) may cause health effects including:
- Skin burns
- Tissue damage
- Temporary headaches or dizziness (for very high exposure)
5. What are electromagnetic waves made of?
Electromagnetic waves are made up of oscillating electric fields and magnetic fields that are perpendicular to each other and to the direction of travel. Both fields carry energy together through space.
6. What is the speed of electromagnetic waves in a vacuum?
All electromagnetic waves travel at the speed of light in a vacuum, which is approximately 3 x 108 meters per second (300,000,000 m/s).
7. How are electromagnetic waves produced?
Electromagnetic waves are produced when an electric charge accelerates, causing its electric and magnetic fields to oscillate and radiate energy outward in the form of a wave.
8. Name the types of electromagnetic waves in the electromagnetic spectrum.
The electromagnetic spectrum includes the following waves, listed in order of increasing frequency: radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays.
9. What devices are used to test for electromagnetic waves?
Common devices used to detect or test for electromagnetic waves include:
- Electromagnetic field (EMF) meters for radio waves and microwaves
- Photodetectors for visible and ultraviolet light
- Geiger counters for X-rays and gamma rays
10. What is the main characteristic of electromagnetic waves?
Electromagnetic waves are transverse waves consisting of varying electric and magnetic fields, they do not need any medium, and travel at the speed of light in a vacuum.
11. Why do electromagnetic waves not need a medium to travel?
Unlike mechanical waves, electromagnetic waves are not vibrations of particles but interactions between electric and magnetic fields. This allows them to travel even through a vacuum, such as space.
12. What is the relationship between wavelength and frequency of electromagnetic waves?
The wavelength and frequency of an electromagnetic wave are inversely proportional. As frequency increases, wavelength decreases, following the formula: speed = wavelength × frequency.
