Engineering Physics - Chapter 1: Modern Physics

This chapter is useful for BTech CSE Semester 1 students preparing Modern Physics for PTU / IKGPTU exams. It helps in revising blackbody radiation, photoelectric effect, Compton effect, wave-particle duality, and matter waves in one place.

Why Study This Chapter

• important for short notes, definitions, and derivation-based questions
• useful for photoelectric effect and Compton effect exam answers
• builds the foundation for Quantum Mechanics in the next chapter
