Question-1. What is meant by interference of light?
Answer-1: When the two waves superimpose over each other, resultant intensity is modified. The modification in the distribution of intensity in the region of superposition is called interference.
Question-2. Is there is any energy loss in interference phenomenon?
Answer-2: No, there is only redistribution of energy ie, energy from dark places is shifted to bright places
Question-3. What are interference fringes?
Answer-3: They are alternately bright and dark patches of light obtained in the region of superposition of two wave trains of light.
Question-4. What is the shape of fringes in wedge shaped film?
Answer-4: The fringes in wedge-shaped film are straight line fringes.
Question-5. What type of source is required in division of amplitude?
Answer-5: In division of amplitude a broad source is required so that the whole firm may be viewed together.
Question-6. Are the fringes equispaced?
Answer-6: Yes, the fringes equispaced.
Question-7. What type of air film do you get when thin plate is placed between two plane parallel glass plates?
Answer-7: A wedge shaped air film is formed. That thickness of the film increases from the end where plates are in contact to the other end.
Question-8. What is shape of interference fringes?
Answer-8: Fringes are straight.
Question-9. How interference does take place in case of air wedge?
Answer-9: Interference occurs between the rays reflected at the upper and lower surface of the air film.
Question-10. Why are Newton's rings circular but air wedge fringes straight?
Answer-10: It depends on the shape of the lens/glass plate placed over the lower glass plate. In Air wedge experiment, the air film is formed between two glass plates but in the case of newton's ring experiment it is formed between the lens which has the curved surface and glass plate so that the film has an increasing radius from the point of contact of lens and plate.
