The distance between two consecutive crests is 3 cm
=> wavelength (L) = 3cm
============================
Ripples cover a distance of 25.2 cm in 1.2 sec
=> wave velocity = distance/time = 25.2/1.2 = 21 cm/s
===========================
velocity = frequency × wavelength
=> frequency = velocity / wavelength
=> frequency = 21/3 = 7 Hz
Thus,
wavelength = 3cm
frequency = 7 Hz
velocity = 21 m/s
=> wavelength (L) = 3cm

3 cm is the distance between two consecutive crests
3cm is the wavelength
___________________________________________________
25.2 cm in 1.2 sec is the ripples covered distance
25.2/1.2 = 21 cm/s = wave velocity = distance/time.

Formula:-
Velocity = frequency × wavelength
Frequency = velocity / wavelength
•°•Frequency = 21/3 = 7 Hz
___________________________________________________
Hence,
- Wavelength = 3cm
- Frequency = 7 Hz
- Velocity = 21 m/s
