Frequency, f = 150 Hz;
As per the question demand we need at least two values to calculate all the given amplitude, wavelength and speed.
on the basis of this question just calculate only time perido of the wave.
T = 1/f
T = 1/150 sec

(a)
Frequency f is reciprocal of time period T
f=1/T
So
T=1/f
As f=150Hz
T=1/150Hs
T=0.00667 second
(b)
Wavelength is equal to
Wavelength=v/f
Where v is speed and f is frequency of the waves.
(c)
Speed v is
v=wavelength×f
Frequency f is reciprocal of time period T
f=1/T
So
T=1/f
As f=150Hz
T=1/150Hs
T=0.00667 second
(b)
Wavelength is equal to
Wavelength=v/f
Where v is speed and f is frequency of the waves.
(c)
Speed v is
v=wavelength×f
