Determining the Speed of Water Waves using a Ripple Tank

The video tutorial demonstrates an experiment to measure the speed of water waves using a ripple tank. It explains how to set up the tank, use a vibrating beam to generate waves, and observe wave shadows to estimate frequency and wavelength. The tutorial guides viewers through calculating wave speed by multiplying frequency and wavelength, providing a practical understanding of wave dynamics.

What is the primary purpose of using a ripple tank in the experiment?

• To generate and observe water waves

• To heat the water

• To measure the depth of water

• To filter impurities from the water

Why is the motor speed reduced during the experiment?

• To make the waves more visible

• To increase the number of waves

• To save energy

• To decrease the number of waves for accurate counting

How is the frequency of the waves determined?

• By measuring the temperature of the water

• By measuring the height of the waves

• By observing the color of the waves

• By counting the number of waves in 10 seconds and averaging

What tool is used to estimate the wavelength in the ripple tank?

• A magnifying glass

• A stopwatch

• A 10 centimeter ruler

• A thermometer

What is the final step in calculating the speed of the waves?

• Multiplying frequency by wavelength

• Adding frequency and wavelength

• Subtracting wavelength from frequency

• Dividing frequency by wavelength
