Question

Plz tell me the correct answer of question 2 and 3 i am in a hurry, plz answer question 3 and 5​

Answer 1

Answer:

2.As a wave enters shallow water, wave height increases and wavelength de- creases. As the ratio of wave height to wavelength, called wave steepness, increases, the wave becomes less stable.

3.In constructive interference, a crest meets a crest or a trough meets a trough, resulting in a larger crest or trough. In destructive interference, a crest meets a trough and results in cancellation hence a smaller disturbance than either of the two interacting waves.
