Required Practical 8: Ripple Tank

What is a ripple tank used for?

• Observing features of water waves

• Measuring the speed of water waves

• Creating waves across the surface of the water

• Recording the frequency of water waves

How do we measure the wavelength of the waves?

• Counting the number of waves passing a point in one second

• Recording the waves using a mobile phone

• Measuring the distance between one wave and 10 waves further

• Freezing the image of the waves

What is the wavelength of the waves in the given example?

• 0.26 centimeters

• 0.026 meters

• 0.0026 meters

• 0.00026 meters

How do we find the frequency of the waves?

• Counting the number of waves passing a point in 10 seconds

• Recording the timer as well as the waves

• Measuring the time it takes for a wave to move the length of the tank

• Dividing the distance traveled by the time taken

What is the frequency of the waves in the given example?

• 0.24 waves per second

• 2.4 waves per second

• 24 waves per second

• 240 waves per second

How do we determine the speed of the waves?

• Multiplying the frequency by the wavelength

• Dividing the wavelength by the frequency

• Measuring the time it takes for a wave to move the length of the tank

• Counting the number of waves passing a point in one second

What is the wave speed in the given example?

• 0.00624 meters per second

• 0.0624 meters per second

• 0.624 meters per second

• 6.24 meters per second

What is another method to determine the wave speed?

• Measuring the distance traveled by the wave

• Dividing the distance traveled by the time taken

• Counting the number of waves passing a point in 10 seconds

• Recording the timer as well as the waves
