Hello Arun,

Following are the detailed information about the Chapters which are there for mains but not in advanced.

Topics included from JEE Main but not in JEE Advanced Physics

1. Electronic Devices: Semiconductors; semiconductor diode: I-V characteristics in forward and reverse bias; diodes as a rectifier; I-V characteristics of LED, photodiode, solar cell and diode; Zener diode as a voltage regulator. Junction transistor, transistor action, characteristics of a transistor; transistor as an amplifier (common emitter configuration) and Oscillator. Logic gates (OR, AND, NOT, NAND and NOR). Transistor as a switch.
2. Electromagnetic Waves: Electromagnetic waves; Characteristics of Electromagnetic Waves; Transverse nature of electromagnetic waves; Electromagnetic spectrum; Applications of Electromagnetic waves
3. Communication Systems: Electromagnetic waves’ propagation; Amplitude and Frequency Modulation; Bandwidth of signals & transmission medium; Basic elements of a Communication System (Block Diagram only).
