The reflecting surface in a rod-type electric room heater serves to direct and enhance the distribution of heat generated by the heating element. By reflecting thermal radiation towards the room, it improves efficiency and increases the effective heating area. This design helps to maximize warmth while minimizing energy loss, ensuring more effective heating for the space.

A shortage of electrons on a surface creates an electric charge imbalance or positive charge. This can lead to the attraction of electrons from neighboring surfaces to balance the charge and create an electric field.
Newton: " the angle of incidence equals the angle of refraction."
The Gauss theory, also known as Gauss's law, is a fundamental principle in physics that relates the distribution of electric charge to the resulting electric field. It states that the total electric flux through a closed surface is proportional to the total electric charge enclosed by that surface, divided by a constant. This law is a powerful tool for understanding the behavior of electric fields and is used extensively in electromagnetism.
convex mirror
The reflecting surface of a mirror is flat.
A CONCAVE mirror is a mirror with a reflecting surface that curves inward.
A mirror is a good reflecting surface as it is designed to produce clear and accurate reflections due to its smooth and highly reflective surface. Glass with a silvered coating also works well as a reflecting surface for various applications.

S and p polarized light refer to the orientation of the electric field in a light wave. S polarized light has the electric field perpendicular to the surface it is reflecting off of, while p polarized light has the electric field parallel to the surface. This difference affects how the light interacts with surfaces and materials.

As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
The surface integral of the electric field is the flux of the electric field through a closed surface. Mathematically, it is given by the surface integral of the dot product of the electric field vector and the outward normal vector to the surface. This integral relates to Gauss's law in electrostatics, where the total electric flux through a closed surface is proportional to the total charge enclosed by that surface.
