Ripple Tank and Wave Phenomena Quiz

What is the primary purpose of the transparent base in a ripple tank?

• To support the sponge

• To hold the water in place

• To prevent water from spilling

• To allow light to pass through for observation

How does the deeper affect the type of wave produced in a ripple tank?

• It changes the water temperature

• It alters the wave speed

• It determines the wave shape

• It affects the wave frequency

What is the function of the eccentric motor in a ripple tank?

• To produce light

What is the main role of a stroboscope in observing waves?

• To amplify wave height

• To change wave direction

• To freeze the motion of waves

• To increase wave speed

How does a stroboscope make waves appear stationary?

• By matching its frequency with the wave frequency

• By increasing the wave amplitude

• By changing the wave direction

• By altering the wave speed

What causes the formation of dark and bright bands on the screen in a ripple tank?
