The answer is 0.025J.
W=1/2*k*x^2
W=1/2*20*0.050^2
W=0.025J
E. Nonsense longitudinal waves have all of these properties
Answer:
A constant value everywhere in the universe.
Explanation:
The speed of light in a vacuum is a constant value. It is not affected by change in frequency or wavelength of the light.
Mathematically the speed of light is given as:
c = λf
where λ = wavelength and f - frequency
The speed of light is the constant of proportionality between frequency and wavelength. In order words, wavelength and frequency are inversely proportional. As the wavelength increases, frequency decreases and vice versa.
While the change in wavelength and frequency of light affect the energy of the light, its speed is a constant value as long as the medium is a vacuum.
The speed of light is also not dependent on the manner with which the light wave is moving.
Based on the nature of constructive interference,
none of the wave intersections will produce constructive interference.
<h3>What is constructive interference?</h3>
Constructive interference is interference that occurs when two waves of the same frequency amplitude and wavelength travelling in the same direction are superposed with the resultant effect of reinforcement of both waves to produce a larger wave.
Constructive interference occurs when the path difference between two identical waves at a point is:
where n = 0, 1, 2, ...
For the various intersections:
- 1.77 cm crest intersecting with a 0.65 cm crest; n = 1.77/0.65 = 2.7
- A 1.2 mm crest intersecting with a 3.9 mm trough is destructive.
- A 4.55 N trough intersecting with a 1.59 N trough; n = 4.55/1.59 = 2.8
- A 0.44 inch trough intersecting with a 0.72 inch crest is destructive.
- A 7.42 mm trough intersecting with a 1.93 mm trough; n = 7.42/1.93 = 3.8
Therefore, none of the wave intersections will produce constructive interference
