Read the given passage and answer the questions that follow based on the passage and related studied concepts. If you drop a stone into a pond, ripples spread across the surface. The tiny waves carry energy but there is no flow of water across the pond. This wave effect is the result of up and down motions in the water. Waves are not only found on water. Sound travels as waves, so does light. Sound is a longitudinal wave form which travel by forming compressions and rarefaction along the direction of propagation. The speed of the waves is measured in m/s. Frequency is the number of waves passing any point per second. If the frequency is 5 Hz, then its time period is 1/5 s (0.2 s). The distance between two consecutive compressions or two consecutive rarefactions is called the wavelength of the wave. Amplitude is the maximum distance that a point moves from its rest position when a wave passes. The speed, frequency and wavelength of any set of waves are linked by the equation : Speed = Frequency × Wavelength The waves in A below are travelling across water.
