What is the smallest distance between the speakers for which the interference of the sound waves is destructive?
ankoles [38]

Answer:Half the wavelength

Explanation: Destructive Interencce is a type of wave superimposition which involves opposing waves, in this case the Trouph of one wave aligns with the crest of the opposing wave. In this case the smallest distance for the maximum destructive wave to take place is have the wavelength,if the wavelength is one lambda the smallest wavelength for the maximum destructive wave to occur is half the wavelength.

A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surfac
Sedbober [7]

Answer:

v = 1.2 m/s

Explanation:

The wavelength of the waves is given as the horizontal distance between the crests:

λ = wavelength = 5.5 m

Now, the time period is given as the time taken by boat to move from the highest point again to the highest point. So it will be equal to twice the time taken by the boat to travel from highest to the lowest point:

T = Time Period = 2(2.3 s) = 4.6 s

Now, the speed of the wave is given as:

v = f\lambda

where,

v= speed of wave = ?

f = frequency of wave = \frac{1}{T} = \frac{1}{4.6\ s} = 0.217\ Hz

Therefore,

v = (0.217\ Hz)(5.5\ m)\\

<u>v = 1.2 m/s</u>
