Answer:308 N/m
Explanation:
Given
mass![\left ( m\right )=0.129 kg](https://tex.z-dn.net/?f=%5Cleft%20%28%20m%5Cright%20%29%3D0.129%20kg)
wavelength![\left ( \lambda \right )=3.86\times 10^7](https://tex.z-dn.net/?f=%5Cleft%20%28%20%5Clambda%20%5Cright%20%29%3D3.86%5Ctimes%2010%5E7)
We know frequency =![\frac{c}{\lambda }=\frac{3\times 10^8}{3.86\tmes 10^7}](https://tex.z-dn.net/?f=%5Cfrac%7Bc%7D%7B%5Clambda%20%7D%3D%5Cfrac%7B3%5Ctimes%2010%5E8%7D%7B3.86%5Ctmes%2010%5E7%7D)
f=7.772 Hz
As the frequency of radio waves is same as the frequency at which object oscillates
![f=\frac{1}{2\pi }\sqrt{\frac{k}{m}}](https://tex.z-dn.net/?f=f%3D%5Cfrac%7B1%7D%7B2%5Cpi%20%7D%5Csqrt%7B%5Cfrac%7Bk%7D%7Bm%7D%7D)
![7.772=\frac{1}{2\pi }\sqrt{\frac{k}{0.129}}](https://tex.z-dn.net/?f=7.772%3D%5Cfrac%7B1%7D%7B2%5Cpi%20%7D%5Csqrt%7B%5Cfrac%7Bk%7D%7B0.129%7D%7D)
![7.772\times 2\times \pi =\sqrt{\frac{k}{0.129}}](https://tex.z-dn.net/?f=7.772%5Ctimes%202%5Ctimes%20%5Cpi%20%3D%5Csqrt%7B%5Cfrac%7Bk%7D%7B0.129%7D%7D)
![k=307.70\approx 308 N/m](https://tex.z-dn.net/?f=k%3D307.70%5Capprox%20308%20N%2Fm)
Earths plates move, creating them to rub together to create earthquakes, and volcanoes occur because magma melts rocks and the pressure is so intense it causes the lava to leak out of the top of a mountain

Explanation:
Chromatic aberration is the result when the lens fail to focus all the colors on the same point. The light then focuses in different points,and could lead to causing two images at once. The main culprit of this is usually dispersion.
