Question

what is Wave Motion write any four characteristics of wave motion for 3 months

Answer 1

$\huge\mathfrak{Answer:-}$

⭕ A wave motion is a means of transferring energy from one point to another point without any actual transportation of matter between them.✔️

⭕ For example :- When we throw a piece of cork on the surface of water, we observe that the cork moves up and down as the wave passes, but the piece does not travel along with waves.

⭕ The water waves carries energy but there is no transfer to matter, thus in a wave motion, disturbance travels through medium but medium does not travels with disturbance.✔️

• ⭕ The distance between two adjacent crest or trough of wave is known as wave length. It is represented by lambda.

• ⭕ Time taken by the wave to travel a distance equal to one wavelength is known as time period.If c is speed of wave then c = lambda/time.✔️

• ⭕ Number of oscillations per second or per unit time is known as frequency. V = C/ lambda.❤️

Answer 2

Answer:

Characteristics of wave motion are :

(i) A wave is produced by the periodic disturbance at a point in the medium.  

(ii) Due to propagation of wave in a medium the particles of medium vibrate about their mean  

positions and energy is transferred with a constant speed from one place to another.
