Question

B) DEFINE THE FOLLOWING:- (2M)

1)Wave length. 2) Tide​

Answer 1

Answer:

the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.

Tides are caused by gravitational pull of the moon and the sun.  Tides are very long-period waves that move through the oceans in response to the forces exerted by the moon and sun. Tides originate in the oceans and progress toward the coastlines where they appear as the regular rise and fall of the sea surface.

Have a nice day :)

Answer 2

Answer:

1. Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave

2.Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun, and the rotation of the Earth.
