Answer:
1.wave - a wave is a disturbance produced in a medium that carries energy from one part of the medium to another part of the medium without the transfer of matter. 2.Transverse wave- a wave in which the particles of the medium vibrate up and down , that is perpendicular to the direction in which the wave is moving Is called transverse wave.
Longitudinal wave- a wave in which the particles of the medium vibrate to and fro in the same direction in which the wave is moving Is called longitudinal wave.
3.loudness and amplitude are related because as the sound is percieved as louder if the amplitude increases and softer is the amplitude decreases . the amplitude of a wave is related to the amount of energy it carries . a high amplitude wave a large amount of energy a low amplitude wave carries a small amount of energy.
4.time period of a wave is the time taken by it to complete one vibration. Please mark me as a brainliest
