## FAQs on 6 Days Study Plan: Ray Optics and Optical Instruments - Physics Class 12 - NEET

 1. What are Maxwell's Equations?
Ans. Maxwell's Equations are a set of four fundamental equations that describe the behavior of electric and magnetic fields. They are named after James Clerk Maxwell, who formulated them in the 19th century. The equations relate the electric and magnetic fields to their sources, such as charges and currents, and describe how these fields interact and propagate.
 2. What is the concept of displacement current?
Ans. Displacement current is a concept introduced by Maxwell to modify Ampere's law. It is a term that represents the time-varying electric field that can produce a magnetic field. According to Maxwell's modification, the total current flowing through a closed loop is the sum of the conduction current (due to moving charges) and the displacement current (due to time-varying electric fields).
 3. What are the properties of electromagnetic waves?
Ans. Electromagnetic waves have several properties, including: - They are transverse waves, meaning that the oscillations of the electric and magnetic fields are perpendicular to the direction of wave propagation. - They can travel through vacuum or any medium that is transparent to them. - They have a constant speed in a vacuum, which is the speed of light. - They can be reflected, refracted, diffracted, and polarized. - They can carry energy and momentum.
 4. What is total internal reflection and how does it occur in mirrors?
Ans. Total internal reflection occurs when a light ray traveling from a medium with a higher refractive index to a medium with a lower refractive index is incident at an angle greater than the critical angle. In the case of mirrors, total internal reflection does not occur as mirrors have a refractive index greater than the surrounding medium. Instead, mirrors reflect light according to the law of reflection, where the angle of incidence is equal to the angle of reflection.
 5. How does refraction occur at spherical surfaces and lenses?
Ans. Refraction at spherical surfaces and lenses occurs due to the change in the direction and speed of light as it passes through different media. When light travels from a medium with a lower refractive index to a medium with a higher refractive index, it bends towards the normal. Conversely, when light travels from a medium with a higher refractive index to a medium with a lower refractive index, it bends away from the normal. This bending of light is responsible for the focusing effect of lenses and the formation of images in optical instruments.
