Question

Assertion (A): As the waves approach the shore, they slow down.

Reason (R): The force of friction acts between the wave and the sea floor.

Options

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for A.

• A is true and R is false.

• A is false and R is true.

Answer 1

Both A and R are true and R is the correct reason for A.

Explanation:

Waves slow down near the shore because the water depth decreases and the wave base starts to touch the sea floor. The friction between the sea floor and the wave reduces its speed and causes it to slow down as it approaches the shore.
