That's more than 275 million stars per day in the observable universe. Stars keep themselves fueled. They fuse elements together to make new elements.Once the star runs out of hydrogen, the helium atoms fuse together to make carbon.
The energy of an electromagnetic wave is typically emitted in short bursts referred to as photons.
<h3>What is electromagnetic energy?</h3>
Electromagnetic energy can be defined as form of energy that is primarily carried by electromagnetic waves such as:
This ultimately implies that, an electromagnetic energy refers to a form of energy that typically moves as particles at the speed of light, which is about three hundred million meters per seconds (3 × 10⁸ m/s).
In conclusion, we can infer and logically deduce that the energy of an electromagnetic wave is typically emitted in short bursts referred to as photons.
