If slit separation is � and screen distance is �, calculate fringe width. In a diffraction experiment, slit width is given. Find the angular position of first minima. Calculate Brewster angle for glass of refractive index 1.5. VERY SHORT ANSWER (1–2 Marks) Write the formula for fringe width in YDSE. What happens to interference pattern if one slit is closed? Define diffraction. Can interference be obtained from a single source? Why? Name the phenomenon that proves the wave nature of light. What type of waves show polarization? IMPORTANT (Short Answer – 3 Marks) What is interference of light? Write two conditions for sustained interference. Define coherent sources of light. What is fringe width? On what factors does it depend? Distinguish between interference and diffraction (any three points). What is polarization? Why can sound waves not be polarized? Define Brewster angle. Write its importance. What is the effect on fringe width if: Explain Huygens’ Principle. Using it, derive the laws of reflection and refraction of light. Derive the expression for fringe width in Young’s Double Slit Experiment (YDSE). Explain Young’s Double Slit Experiment with neat diagram. What is the condition for constructive and destructive interference? What is diffraction of light? Explain diffraction due to a single slit and derive the condition for minima. Describe the phenomenon of polarization. Explain Brewster’s Law and obtain its expression.
