Answer:
Given that,
Formula of sound
We need to calculate the formula of sound
(1). Echo :
Speed of echo is equal to the twice of distance between surface and source divided by time.
In mathematically term,
v=\dfrac{2d}{t}v=
t
2d
Where, v = echo
d = distance between surface and source
t = time
(2). Velocity of wave :
Velocity of wave is equal to the product of frequency and wavelength.
In mathematically term,
v=f\lambdav=fλ
Where, v = velocity of wave
f = frequency
\lambdaλ = wavelength
(3). Frequency :
Frequency is reciprocal of time.
In mathematically term,
f=\dfrac{1}{t}f=
t
1
Where, f= frequency
t = time
(4). Energy of wave :
Energy of wave is equal to the product of planck constant and frequency.
In mathematically term,
E=h\nuE=hν
Where, h = planck constant
\nuν = frequency
(5). Frequency of stretched string :
Frequency of stretched string is defined as
f=\dfrac{1}{2L}\sqrt{\dfrac{T}{M}}f=
2L
1
M
T
Where, f = frequency
L = length of string
T = tension
M = mass per unit length
Hence, This is the required solution
