1.	In a ripple tank 12 ripples are produced in one second . If distance between crest and next trough is 10cm find :a) wavelength b) frequency c) velocity of the wave.
Answer» WAVELENGTH OF WAVE IS DISTANCE MOVED DURING ONE OSCILLATION. Distance between crest and next trough is HALF of the wavelength.Therefore wavelength is λ = 2 × 10 cm= 20 cm . *FREQUENCY = ν = NUMBER OF RIPPLES PER SEC = 12/SEC = 12 HZ* . Velocity of wave = *ν ×λ* = 12/sec × 0·2m = 2·4 m/sec =
