The frequency of Tropical tide on Tropic of cancer comes _____ in a synodic month.

Question

Accepted Answer

The frequency of Tropical tide on Tropic of cancer comes 2 times in a synodic month.

Here's why Option 4 is the correct answer and why the other options are incorrect:

*   **Option 4: 2 times (Correct)** Tropical tides are influenced by the Moon's declination, which is its angular distance north or south of the equator. The Moon reaches its maximum northern and southern declination twice during a tropical month (which is very close to a synodic month). When the Moon is at its maximum declination (either north or south), the tidal bulge is concentrated at the corresponding latitude. The Tropic of Cancer experiences a stronger tidal force when the Moon is at its maximum northern declination. Since this happens roughly twice a synodic month (once when the Moon reaches its maximum northern declination and once when it reaches its maximum southern declination, although the effect is less pronounced when the Moon is at its maximum southern declination for the Tropic of Cancer), the frequency of tropical tides is approximately two times per synodic month.

*   **Option 1: 8 times (Incorrect)** This is far too frequent. The major tidal influences are the Moon's position and phase, which don't cycle that rapidly.

*   **Option 2: 4 times (Incorrect)** While there are two high tides and two low tides per day in many locations, the *tropical* tide specifically relates to the Moon's declination and its effect on tidal bulges at specific latitudes. The Moon's maximum declination doesn't occur four times in a synodic month.

*   **Option 3: only one time (Incorrect)** The Moon reaches a maximum declination twice in a tropical month (north and south), so the effect on the Tropic of Cancer is felt more than once.
