(a) The amplitude of the wave is 3 cm.
(b) The speed of the wave is 19.6 m/s
(c) The angular frequency is 653.72 rad/s.
(d) The period of the wave is 0.0096 s.
(e) The wavelength of the wave is 0.392 m.
<h3>
Speed of the wave</h3>
The speed of the wave is calculated as follows;
where;
- μ is mass per unit length = (0.26 kg)/(2 m) = 0.13 kg/m
- T is tension
<h3>Angular frequency</h3>
ω = v/r
ω = v/A
ω = 19.6/0.03
ω = 653.72 rad/s
<h3>Period of the wave</h3>
<h3>Wavelength</h3>
v = fλ
λ = v/f
λ = 19.6/50
λ = 0.392 m

Answer:
Doppler effect changes the wavelength of the light emitted, depending upon whether source is moving away or coming towards the observer(detector).
Explanation:
Doppler effect in light is actually a relativistic effect but somewhat similar to the one which happens in sound waves.
When the source is moving away from the detector, the wavelength of the light emitted from the source appears to be increased as seen by the detector, as a result the frequency decreases(we know that frequency of light= speed of light/wavelength of light. Here speed of light is constant and frequency of light is inversely proportional to its wavelength)
Due to this decrease in frequency the light emitted from the source appears more red, since red color is on low frequency side in the electromagnetic spectrum.
Similarly for the source moving towards the detector, the wavelength appears to be decreased, thereby resulting in increase in frequency and the source appears blue. The shift in frequency is known as doppler shift.
The shift in frequency when the source is moving away is known as redshift and the one where the source is moving towards detector is known as blueshift

Explanation:
Initial speed of the rocket, u = 0
Acceleration of the rocket,
Time taken, t = 3.39 s
Let v is the final velocity of the rocket when it runs out of fuels. Using the equation of kinematics as :
Let x is the initial position of the rocket. Using third equation of kinematics as :
Let is the position at the maximum height. Again using equation of motion as :
Now and v and u will interchange
x = 524.14 meters
Hence, this is the required solution.
