उत्तर
| Transverse waves | Long itud ina I waves |
| 1. In these waves, the vibrations of the particles are perpendicular to the direction of wave and form crest and trough in the medium. | 1. In these waves, the vibrations of the particles are along the direction of propagation of wave and form compress ons and rarefactions in the medium |
| 2. These waves can be formed only in the medium which possesses rigidity. Hence, they can travel only in soIids and on the surface of liquids. | 2. These waves can travel in solids, liquids as well as gases. |
