Waves: fifth question

Minute after minute, hour after hour, day after day, ocean waves continue to splash onto the shore. Explain why the beach is not completely submerged and why the middle of the ocean has not yet been depleted of its water supply.

In order for John to hear Jill, air molecules must move from the lips of Jill to the ears of John.

Do you agree with the previous statement? Explain, referring to the definition of wave.

Waves: Second question

A picture of a wave generated through a slinky. Is it possible to find out the amplitude of the wave? Answer the question referring to the definition of amplitude. If yes, suggest a method to determine the amplitude by the picture, if no, motivate your answer.

Waves - first question

A nice picture of ripples on a pond. Is it possible to find out the period of the wave? Answer the question referring to the definition of period. If yes, suggest a method to determine the period by the picture, if no, motivate your answer.
