Answer:
The ratio is 9.95
Solution:
As per the question:
Amplitude, 
Wavelength, 
Now,
To calculate the ratio of the maximum particle speed to the speed of the wave:
For the maximum speed of the particle:

where
= angular speed of the particle
Thus

Now,
The wave speed is given by:

Now,
The ratio is given by:


I believe it is C hope i helped!
Answer:
A wave in which the medium vibrates at right angles to the direction of the propagation is called transverse wave.
Linear expansivity, area expansivity and volume or cubic expansivity are
