# JEE Main Oscillations and Waves Revision Notes

View Notes

We can define the wave motion as the disorder that originated in the medium because of the frequent periodic motion of the atoms of the medium and transmitting it from atom to atom. Due to this transmission, the particles remain vibrating about themselves and their mean positions.

Wave Equation: $\frac{d^{2}y}{dt^{2}} = v^{2} (\frac{d^{2}y}{dx^{2}})$

Q1. Mention the Second Kind of Waves.

Ans: As per scientific experiments, electromagnetic waves are classified into seven basic types such as,

• Microwaves

• Visible Light Rays

• Ultraviolet Waves

• Infrared Waves

• Gamma Rays

• X - rays

Q2. What are the Features of the Oscillation of Waves?

Ans: The oscillating waves lie perpendicular to the direction where oscillation takes place for transverse waves. The wave transfers energy, instead of moving in the direction of propagation.

Q3. What is the Contribution of Vedantu for the JEE Aspirants?

Ans: Vedantu is contributing to the study program for subjects like Physics, Chemistry, Mathematics, and Biology. The perception along with detailed question and answer practice papers facilitates a better understanding of concepts for JEE aspirants. The mock tests and practice papers are prepared as per the latest JEE pattern to help the students to score more.

Q4. What Facilities Does Vedantu Offer?
