What do radio waves, microwaves, light, and x-rays have in common?
2 answers:
Answer:
Microwaves
Light Waves
Radio Waves
X Rays
All above are different energy range of electromagnetic waves
So all of the above have many common properties as following
1. All of the above will travel at speed of in vacuum or air
2. All above can travel without any medium as they propagate in form of electric field and magnetic field
3. All waves have effect of medium on their wavelength and speed
4. All waves have no effect on frequency due to change in medium

<h2>Answer:Displacement</h2>
Explanation:
Potential energy is present in a spring because the spring is elongated and some work is done it to elongate it.
The elastic potential energy present in a spring is given by
where is the spring constant.It may vary from spring to spring and
is the displacement of the spring from its equalibrium position.
It is evident from the equation that potential energy in the spring increases as increases.
