Answer:
gravitational waves are ripples in spece-time caused primarily when objects are accelerated and the energy for the acceleration is transpoted as gravitational radiation.
they are difficult to detect because they require very sensitive technology or you will have to wait unitl black holes collide.
Answer:
![\lambda=4.81\times 10^{-8}\ m](https://tex.z-dn.net/?f=%5Clambda%3D4.81%5Ctimes%2010%5E%7B-8%7D%5C%20m)
Explanation:
We have,
The surface temperature of the star is 60,000 K
It is required to find the wavelength of a star that radiated greatest amount of energy. Wein's displacement law gives the relation between wavelength and temperature such that :
![\lambda T=2.89\times 10^{-3}](https://tex.z-dn.net/?f=%5Clambda%20T%3D2.89%5Ctimes%2010%5E%7B-3%7D)
Here,
= wavelength
![\lambda=\dfrac{2.89\times 10^{-3}}{60000}\\\\\lambda=4.81\times 10^{-8}\ m](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7B2.89%5Ctimes%2010%5E%7B-3%7D%7D%7B60000%7D%5C%5C%5C%5C%5Clambda%3D4.81%5Ctimes%2010%5E%7B-8%7D%5C%20m)
So, the wavelength of the star is
