Why do scientist believe that dark matter does not interact through the electromagnetic force?
Here is the simple simple answer. If dark matter did interact via the electromagnetic force, it would EMIT some light since light is the tell-tale evidence of electromagnetic interaction. This is known to not be the case. Also, and perhaps more importantly, if dark matter did interact electromagnetically it would ABSORB light from distant stars. This is known to not be the case since we don't see unexpected absorption lines in the spectra from stars in our galaxy or other galaxies.

How do electric and magnetic fields interact and influence each other in the context of electromagnetic phenomena?
Electric and magnetic fields interact and influence each other through electromagnetic phenomena. When an electric field changes, it creates a magnetic field, and vice versa. This relationship is described by Maxwell's equations, which show how these fields are interconnected and how they propagate through space as electromagnetic waves.
Where do electromagnetic waves transfer energy?
Electromagnetic waves transfer energy through oscillating electric and magnetic fields. As the waves travel through a medium or through space, they can transfer energy to objects that absorb or interact with them. This energy transfer is the basis for various applications of electromagnetic waves, such as in communication, heating, and lighting.
How does the transfer of energy through electromagnetic waves occur?
Electromagnetic waves transfer energy through a combination of electric and magnetic fields that oscillate perpendicular to each other. When these waves travel through space, they can interact with objects and transfer their energy through absorption or reflection.
What must happen in order for an electromagnetic wave to form?
An electromagnetic wave is formed when an oscillating electric field creates an oscillating magnetic field, and vice versa. When these two fields interact and propagate through space, they form an electromagnetic wave.
How do electromagnetic waves carry and transfer energy through space?
Electromagnetic waves carry and transfer energy through space by oscillating electric and magnetic fields. As the waves travel, they create a changing electromagnetic field that can interact with charged particles, transferring energy to them. This process allows electromagnetic waves to carry energy over long distances without the need for a medium to propagate through.
Does the atomic nucleus contain particles that interact with other atoms?
Yes, the atomic nucleus contains protons and neutrons which interact with other atoms through electromagnetic and nuclear forces. Protons carry positive charge and repel other protons, while neutrons stabilize the nucleus. These interactions determine the properties of the element and its behavior in chemical reactions.
How is energy transferred through electromagnetic waves?
Energy is transferred through electromagnetic waves by the movement of electric and magnetic fields. When an electromagnetic wave travels through space, it carries energy in the form of oscillating electric and magnetic fields. This energy can be absorbed by objects that interact with the wave, such as antennas or solar panels, converting it into usable forms of energy.
Light energy travels in electromagnetic waves How do electromagnetic waves emit energy?
Electromagnetic waves emit energy through oscillating electric and magnetic fields that propagate through space. This energy transfer occurs as the waves interact with matter, inducing changes in the atoms and molecules that absorb the energy. The absorption of electromagnetic energy can lead to heating, chemical reactions, or the generation of electrical currents.
What is the energy transferred as em waves?
Electromagnetic waves transfer energy through the oscillation of electric and magnetic fields. The energy carried by electromagnetic waves is proportional to their frequency, with higher frequencies carrying more energy. This energy transfer allows electromagnetic waves to propagate through space and interact with matter.
What is the significance of complex permittivity in the study of electromagnetic materials?
Complex permittivity is significant in the study of electromagnetic materials because it describes how these materials interact with electromagnetic fields. It includes both the material's ability to store electrical energy and its ability to dissipate energy as heat. This property is crucial for understanding how electromagnetic waves propagate through and interact with different materials, which is essential for various applications such as telecommunications, radar systems, and medical imaging.
What does the letters in electromagnetic mean?
The letters in electromagnetic refer to the two fundamental components: "electro" stands for electric field and "magnetic" stands for magnetic field. These fields interact with each other to propagate energy and information through space in the form of electromagnetic waves.
What is the significance of the divergence of the electric field in the context of electromagnetic theory?
The divergence of the electric field in electromagnetic theory indicates the presence and distribution of electric charges in a given region. It helps in understanding how electric charges interact and how electromagnetic waves propagate through space.
