Owing to the retardation of the tidal wave in the ocean by frictional force as the earth revolved daily around its axis and as the tide tends to follow the direction of the moon the highest tide for each location is not coincidence with conjunction and opposition but occurs at some constant time after new and full moon. This interval which may amount to as much as 2.5 days is known as

44
Q

True or False

When a wave generated in deep water enters shallow water, the wave encounters a change in water depth which causes the wave to slow down. As the wave slows down, the wave length decreases and the wave height increases, which results in a steeper wave profile. However, the period of wave, which is the time it takes for one complete wave cycle to pass a given point, will decrease. This is because the speed of the wave is directly related to the water depth, and as the water depth decreases, the wave speed decreases as well. Since the period of the wave is determined by the wave speed and wave length, a decrease in wave speed results in a decrease in wave period
