Circular periodic waves can be generated
Correct answer: A. In a ripple tank using spherical dippers
- A. In a ripple tank using spherical dippers
- B. Using electromagnetic vibrator
- C. By giving sudden up and down movement to a rope with one fixed end
- D. All of the above
Explanation
A ripple tank is a shallow glass tank filled with water where waves are generated to study their behavior. By using spherical dippers (small, rounded objects), you can create circular waves on the surface of the water. When these dippers are dipped into the water, they generate concentric, circular waves that spread outward.this is correct option

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
