Do charges (static or moving) reflect light? If no, then how can we see a spark?

The relationship between charges and light reflection is complex and not fully understood. However, it is known that charges, whether static or moving, can cause the emission or absorption of electromagnetic radiation, which includes visible light.
Yes, static charges can reflect light. When a charged object is placed near a light source, the electric field created by the charge can cause the light to change direction and reflect off the object, making it visible to the human eye.
Moving charges can reflect light through a phenomenon known as the Doppler effect. As a charged particle moves, it creates a disturbance in the surrounding electric and magnetic fields, resulting in a change in the frequency of the emitted light. This change in frequency can be detected as a shift in the color of the reflected light.
Yes, charges can reflect light in all directions. The direction of reflection depends on the angle at which the light hits the charged object and the orientation of the electric field of the charge. This phenomenon is known as specular reflection and is commonly observed with smooth surfaces.
Yes, the reflection of light by charges can be affected by the color of the light. This is because different colors of light have different wavelengths and can interact with charges in different ways. For example, shorter wavelengths of light, such as blue and violet, tend to be more easily reflected by charges compared to longer wavelengths like red and orange.
