Question

What will be the wavelength in nm of an X_ray of frequency 2 into 10^18Hz

Answer 1

Explanation:

The solution of this problem is important to classical mechanics, since many naturally occurring forces are central. Examples include gravity and electromagnetism as described by Newton's law of universal gravitation and Coulomb's law, respectively. The problem is also important because some more complicated problems in classical physics (such as the two-body problem with forces along the line connecting the two bodies) can be reduced to a central-force problem.k!d!s!w!!wksks
