Surface Ripple Waves

What is the purpose of the vibrating bar in a ripple tank?

• To measure the temperature of the water

• To heat the water

• To create waves across the water surface

• To measure the depth of the water

What is the role of the sheet of white paper in the ripple tank experiment?

• To create a background for observing waves

• To measure the speed of waves

• To absorb excess water

• To reflect light

How can the wavelength of waves in a ripple tank be measured?

• By measuring the distance between successive waves

• By observing the color of the waves

• By measuring the depth of the water

• By counting the number of waves in a given time

What does the frequency of a wave indicate?

• The distance between two waves

• The number of waves passing a point per second

• The speed of the wave

• The height of the wave

What is the significance of dividing by 10 when measuring frequency?

• To simplify calculations

• To decrease the value

• To increase accuracy

• To convert units

Which equation is used to calculate the speed of water waves?

• Speed = Distance / Time

• Speed = Wavelength / Frequency

• Speed = Frequency / Wavelength

• Speed = Frequency x Wavelength
