As ocean waves approach shore, their velocity decreases. How does a decrease in velocity affect the frequency and wavelength of
2 answers:
As ocean waves approach shore, their velocity decreases, the frequency stays the same and the wavelength decreases.
Explanation:
The velocity, wavelength, and frequency are related by the following mathematical equation:
Velocity = wavelength × frequency
When the waves reach the shore with reduced velocity, the frequency of the waves can be kept constant, only by reducing the wavelength. A direct relationship is established between velocity and wavelength.
Therefore, reduction in the velocity leads to a proportional reduction in the wavelength of the wave, keeping the frequency the same.
Thus, option (D) is the correct answer.

1. Calculate the equivalent resistance in the circuit :
In the given diagram, the resistors are in series connection,
So equivalent resistance = sum of resistance of both resistors.
Therefore, Equivalent resistance = 840 ohms.
2. Calculate the current through the battery :
Hence, current through the battery = 0.142 A
3. How much current is passing through each resistor :
Since the resistors are joined in series connection, the current flowing through each resistor will be equal = 0.142 Amperes.
