The typical semidiurnal period of a solar tide according to equilibrium tidal theory is hours, whereas the semidiurnal lunar tidal period is hours.

24 and 12 h and 12.4 h

Explanation:

For a typical tide of the period of the semidiurnal period for the solar active tides are about 24 and 12 hours as [er the equilibrium tidal theory and those of the semidiurnal lunar tides are about 12.4 hours period of the day. The tidal ranges occur to form the two high to two low tides a day and semi-diurnal has two low tides each and every day.
