[@dhanjaysinghyadav4158]

15:55 But ma'am as according to ncert book y axis represents density or pressure. Mam ,please clear my doubt that whether it represents displacement of particles or pressure and density.?

[@MagnetBrainsEducation]

Thanks for your comment and asking a great question! The y-axis can represent either displacement of particles or pressure and density. It really depends on the context of the problem. For this particular example, the y-axis is representing displacement of particles. I hope this answers your question!

Mam pls tell transverse wave because we will define in exam Regards Jatti khushi 🤗

[@MagnetBrainsEducation]

Hi Khushi! I'm glad you're taking the time to watch our educational videos. Transverse waves are waves that travel at right angles to the direction of their energy. I'm sure if you watch our video about transverse waves, you'll be able to understand it better. Feel free to reach out if you need further help. Good luck with your exams!

Transverse wave samjhao

A wave that vibrates at an angle of 90° to the direction that is moving.

[@niyatighai_2008]

Ma'am also plz tell what can we write in longitudinal and transverse wave if it comes to define in our exam. Regards Niyati

[@MagnetBrainsEducation]

Hello Niyati, Thank you for your comment! Longitudinal waves are when the particles of the medium vibrate parallel to the direction of the wave propagation. Transverse waves are when the particles of the medium vibrate perpendicular to the direction of the wave propagation. I hope this helps you with your exam! All the best!

Hi there! Thanks for watching our educational video! Mechanical waves are waves that require a medium to travel through, such as air or water. Hope that helps! Let us know if you have any other questions.

Where does kinetic energy go , after losing some kinetic energy during the propagation of sound wave by air particles, I ask so because we all know that energy can neither be created nor destroyed.
