Description
The electric field of a plane polarized electromagnetic wave in free space at time t=0 is given by an expression. E→(x,y)=10jˆcos[(6x+8z)]. The magnetic field B→(x,z,t) is given by (c is the velocity of light):
Frequently Asked Questions
How to prepare for IIT-JEE Physics?
To prepare for IIT-JEE Physics, focus on understanding concepts rather than memorizing formulas. Practice solving a variety of problems, especially previous years’ questions. Create a study schedule that covers all topics, with extra time for challenging areas like Mechanics and Electromagnetism. Regular revision and mock tests are essential for success.
How does electromagnetic induction work?
Electromagnetic induction is the process of generating an electromotive force (EMF) in a conductor by changing the magnetic field through it. According to Faradays Law, the induced EMF is proportional to the rate of change of magnetic flux. This principle is the basis for generators, transformers, and inductors, which are essential components in electrical power systems.
What is the difference between reflection and refraction?
Reflection is the bouncing back of light when it hits a surface, following the law that the angle of incidence equals the angle of reflection. Refraction is the bending of light when it passes from one medium to another, governed by Snell’s Law (n₁sin θ₁ = n₂sin θ₂), where n is the refractive index of each medium.
