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.
What is the difference between electric potential and electric potential energy?
Electric potential is the electric potential energy per unit charge, measured in volts (V). It’s a property of a point in space. Electric potential energy is the energy possessed by a charge due to its position in an electric field, measured in joules (J). It depends on both the charge and its position.
What is the difference between transverse and longitudinal waves?
In transverse waves, the particles of the medium vibrate perpendicular to the direction of wave propagation. Examples include light waves and waves on a string. In longitudinal waves, the particles vibrate parallel to the direction of wave propagation. Sound waves and compression waves in springs are examples of longitudinal waves.
