Waves
Flash cards
A wave is a disturbance which propagates in space, transport energy from one place 
to another without the transport of matter.
Example – Ripples on a pond, sound we hear etc.

A wave is a disturbance which propagates in space, transport energy from one place 
to another without the transport of matter.
Example – Ripples on a pond, sound we hear etc.
Classification of wave
Waves can be primarily classified into four categories–
(i) Based on medium
(ii) Based on the motion of particles of the medium
(iii) Based on energy propagation
(iv) Based on direction of propagation

FAQs on Flashcards for JEE Physics - Waves Class 11

1. What are waves?
Ans. Waves are disturbances that transfer energy from one place to another without transferring matter. They can be seen as traveling oscillations or vibrations through different mediums, such as air, water, or even solids.
2. How are waves classified?
Ans. Waves can be classified into two main categories: mechanical waves and electromagnetic waves. Mechanical waves require a medium to travel through, while electromagnetic waves can travel through a vacuum.
3. What are the different types of mechanical waves?
Ans. Mechanical waves can be further classified into three types: transverse waves, longitudinal waves, and surface waves. Transverse waves oscillate perpendicular to the direction of wave travel, longitudinal waves oscillate parallel to the direction of wave travel, and surface waves combine characteristics of both transverse and longitudinal waves.
4. What are some examples of electromagnetic waves?
Ans. Electromagnetic waves include radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays. Each type of electromagnetic wave has a different wavelength and frequency.
5. How do waves interact with matter?
Ans. When waves encounter matter, they can be reflected, absorbed, transmitted, or refracted. Reflection occurs when waves bounce off a surface, absorption happens when waves are absorbed by the medium, transmission occurs when waves pass through a medium, and refraction is the bending of waves as they pass from one medium to another with different densities.
