Explanation:
Let f₁ is the fundamental frequency, 
Lower pitch frequency, 
Fundamental frequency is,
.....(1)
Lower frequency is,
..............(2)
Dividing equation (1) and (2) as :




So, the ratio of linear mass density μ of the string with the higher pitch to that of the string with the lower pitch is 0.00132. Hence, this is the required solution.
'Newton-second' is dimensionally equivalent to 'kilogram-meter/second'.

Explanation:ebebbebebebes
The frequency of the wave has not changed.
In fact, the frequency of a wave is given by:

where v is the wave's speed and
is the wavelength.
Applying the formula:
- In air, the frequency of the wave is:

- underwater, the frequency of the wave is:

So, the frequency has not changed.
