The mass of a neutron is:
Since we know its speed, we can calculate the neutron's momentum:
The problem says the photon has the same momentum of the neutron, p. The photon momentum is given by
where h is the Planck constant, and
is the photon wavelength. If we re-arrange the equation and we use the momentum we found before, we can calculate the photon's wavelength:
And since we know the photon travels at speed of light c, we can now calculate the photon frequency:
O no,O no,O no actualy the point is that I don’t know the answer to the question
Answer:
systems help identify parts and simplify solutions.
Explanation:
Systems are very important in science because they are made up of many parts and can help simplify solutions better.
A system is made up of several parts that are interacting together as a whole. They are very important in solving scientific problems and looking introspectively into a problem.
The parts that makes up the system are equally important as the whole. Systems are typified by what transpires at the level of their parts. Viewing a problem from a system wide angle helps scientists have better knowledge and can be vital in solving scientific problems.
<span>-Electromagnetic waves carry transverse vibrations in electrical and magnetic fields, not vibrating particles.
-Electromagnetic waves do not need matter to travel through - they can travel through empty space (a vacuum).
<span>-In a vacuum, all electromagnetic waves travel at approximately 3 x 108 m/s - the fastest speed possible.
</span><span>-When electromagnetic waves travel through matter (for example, light through air or glass), they travel a bit slower than this but rarely less than half as fast as in a vacuum. The value for light travelling through an optical fibre, for example, is taken as 2 x 108 m/s.</span></span>
