This comprehensive guide provides the most updated HSC Physics Question Bank with Important Questions – Wave Optics 2026 to help you secure top marks.
Chapter Overview and Weightage for 2026
Wave Optics is a cornerstone of the HSC Physics syllabus. For the 2026 academic cycle, the Maharashtra State Board has assigned a significant weightage to this unit. Understanding where to focus your energy is the first step toward a high percentile.
Chapter Name | Weightage (Without Option) | Weightage (With Option) |
Wave Optics | 5 Marks | 7 Marks |
This chapter is known for its high-return potential because the questions are often predictable, ranging from descriptive derivations to application-based numericals.
HSC Physics Question Bank with Important Questions – Wave Optics 2026: The Must-Know List
To rank high in your exams, you must master the following repeated questions analyzed from official previous years' papers and the latest SCERT "Prashnapedhi."
1. Theory and Descriptive Questions (2-3 Marks)
Huygens’ Principle: State and explain Huygens’ principle of secondary wavelets.
Wavefront Types: Distinguish between Spherical, Plane, and Cylindrical wavefronts with neat diagrams.
Brewster’s Law: State the law and explain the concept of the polarizing angle.
Coherent Sources: Define coherent sources of light and explain the conditions for obtaining a steady interference pattern.
Polarization: What is polarization of light? Explain the use of polaroids in daily life (e.g., medical diagnostics or glare reduction).
2. Important Derivations (3-4 Marks)
Laws of Reflection/Refraction: Prove the laws of reflection or Snell’s law using Huygens’ wave theory. (Extremely Important).
Young’s Double Slit Experiment (YDSE): Derive an expression for the fringe width (band width) in the interference pattern.
Diffraction at a Single Slit: Obtain the conditions for the first minimum and secondary maxima.
Resolving Power: Derive the expression for the resolving power of a microscope and telescope.
3. Critical Formula Names for Numericals
While the full derivations are necessary for theory, quick numerical solving requires you to have the following formulas at your fingertips:
Snell’s Law of Refraction
Band Width (Fringe Width) Formula
Path Difference for Bright and Dark Fringes
Brewster's Law Formula
Malus’ Law (Intensity of Transmitted Light)
Resolving Power of Microscope & Telescope
Condition for Diffraction Minima
Medical Applications of Wave Optics
In 2026, the board has emphasized the interdisciplinary nature of Physics. Wave Optics plays a vital role in medical technology. Concepts like Resolving Power are fundamental to the operation of high-end optical microscopes used in pathology and microbiology. Furthermore, Polarization is utilized in medical imaging and the study of chiral molecules in pharmacology, making this chapter crucial for students aspiring for medical entrance exams like NEET.
Expert Preparation Tips for 2026
Diagram Precision: In Wave Optics, a neat, labeled diagram can often earn you 50% of the question's marks even if the theory is brief. Always use a sharp pencil for wavefront diagrams.
Official Resources: Stick to the official Maharashtra State Board (MSBSHSE) textbooks and SCERT question banks.
Numerical Practice: At least 30% of the Wave Optics section will be numerical-based. Focus on YDSE and Brewster’s Law problems.
