This wave is the Periodic wave, we know that because the wave is recurring at regular intervals

This is a Tranverse Wave, we know this since there was a disturbance at a right angle to the direction which the wave will travel

This is a longitudinal wave, we know this because the spring gets compressed and gets let go making a disturbance in the same direction as the direction of the travel

This was a pulse, we know that since there was only one disturbance in the spring
