A periodic wave has a fixed pattern that is repeated. One completion of the wave pattern is called as cycle of the wave.
<u>Explanation:
</u>
Periodic waves are those which repeat the same kind of behaviour or pattern after a particular interval of time. So, completion of behaviour or pattern for a given time interval is termed as the cycle of wave.
Generally, one complete wave pattern makes a time interval of 2π. So each cycle will take nearly 2π time to form. The repetition of cycle in a time interval will help us to derive the frequency of the system.
It could combine with any other metal on the periodic table. If I had answers to choose from, then maybe I could help you better.
Hope this helps!!!

Answer: D) 30</h3>
Angle of incidence always equals angle of reflection. Think of a tennis ball being hit into a wall. The ball will bounce off at the same angle that it approached with. The angles mentioned are formed through the line called the "normal", which is the line perpendicular to the surface.
Answer:
A. Energy
Explanation:
It cannot be B. because from magnetism we get magnetic energy.
I hope this helps you in any way :)
