KNU 4th SEMESTER IMPORTANT QUESTIONS ( WAVES AND OPTICS)

KAZI NAZRUL UNIVERSITY IMPORTANT QUESTIONS (WAVES AND OPTICS) SEMESTER -IV 1. What are the beats? Give an analytical description of the phenomenon of beats and show that the beat frequency is equal to the difference between the frequencies of the component oscillators. 2. Two simple harmonic motions act simultaneously on a particle at right angles to each other. Show that the path of the particle will be an ellipse when the two motions have the same period but different amplitudes and initial phases. What happens when the phase difference between the motions is – i) zero ii) 90 degree iii) 180 degree? 3. What are Lissajous figures? Write down their importance. 4. Discuss the formation of Lissajous figures by the superposition of two simple harmonic motions when i) the periods are the same but the amplitudes and phases are different.ii) the periods are in the ratio 1:2, and amplitudes and phases are different. 5. What are the progressive waves? Derive the mathe
