Longitudinal and Transverse Waves
Longitudinal Waves:
- In longitudinal waves, particles of the medium vibrate in the direction of the waves.
- The portion of wave in which particles of medium are very close to each other is called compression.
- Examples of longitudinal waves are sound wave and seismic waves.
- Distance between the centre of two compressions and rarefactions is called wave-length.
Transverse Waves:
- In transverse waves, particles of the medium vibrate in the direction perpendicular to the direction of wave.
- The portion in which particles of medium are higher than their normal position is called crest.
- Examples of transverse wave are microwaves and radio waves.
- Distance between two crests and troughs is called wavelength.
This phenomenon requires the introduction of new educational technologies, ensuring the flexibility of the educational process, the introduction of software and material and technical support in the field of modern higher education and the appropriate training of the teaching staff. Problems of behavior and social adaptation of the child at school When the student first went to school, it was time to work hard. But here the child often has difficult problems. They can be different: conflicting relationships with classmates, teachers, learning difficulties, refusal to attend lessons. A huge mistake is often made by parents who do not deal with these problems because they are inattentive or very busy. Parents can communicate here.
