Case Study Questions on Wave Optics

Questions

Question 1:

Diffraction of light is bending of light around the corners of an object whose size is comparable with the wavelength of light. Diffraction actually defines the limits of ray optics. This limit for optical instruments is set by the wavelength of light. An experimental arrangement is set up to observe the diffraction pattern due to a single slit.

Read the given passage carefully and give the answer of the following questions:

Q 1. How will the width of central maxima be affected if the wavelength of light is increased?

Q 2. Under what condition is the first minima obtained?

Q 3. Write two points of difference between interference and diffraction patterns.

Two students are separated by a 7 m partition wall in a room 10 m high. If both light and sound waves can bend around obstacles, how is it that the students are unable to see each other even though they can converse easily?

Answers

1. The width of the central maxima is directly proportional to the wavelength, therefore if the wavelength of light is increased, then width of central maxima also increases.

2. Condition for first minima due to a single slit, $a \sin \theta=\lambda$ where, $a=$ width of slit.

3. Differences

Bending of waves by obstacles by a large angle is possible when the size of the obstacle is comparable to the wavelength of the waves. On the one hand, the wavelength of light waves is too small in comparison to the size of the wall. Thus, the diffraction angle will be very small. Hence, the students are unable to see each other. On the other hand, the size of the wall is comparable to the wavelength of the sound waves. Thus, the bending of sound waves takes place at a large angle. Hence, the students are able to hear each other.

Q2: Why are case study questions important for understanding class 12 physics chapters?

A2: Case study questions provide a practical context for students to apply theoretical knowledge to real-world situations, fostering deeper understanding and critical thinking skills.

Q3: How should students approach answering case study questions for CBSE?

A3: Students should carefully read the case study, identify the key issues or problems presented, analyze the information provided, apply relevant concepts and principles of chemical reactions and equations, and formulate well-supported solutions or responses.

Q4: Are there any resources available online for students to practice case study questions on class 12 physics chapters for CBSE exams?

A4: Yes, several educational websites offer case study questions for CBSE students preparing for science examinations. We also offer a collection of case study questions for all classes and subject on our website. Visit our website to access these questions and enhance your learning experience. If you need more case study questions for your preparation, then you visit Physics Gurukul website.

Q5: How can students effectively prepare for case study questions on “Wave Optics” for CBSE exams?

A5: Effective preparation strategies include regular revision of concepts, solving practice questions, analyzing case studies from previous exams, seeking clarification on doubts, and consulting with teachers or peers for guidance and support.

Q6: How can teachers incorporate case study questions on “Wave Optics” class 12 physics into classroom teaching?

A6: Teachers can integrate case studies into lesson plans, group discussions, or interactive activities to engage students in active learning, promote problem-solving skills, and facilitate a deeper understanding of “Wave Optics”.

Q7: When a wave undergoes reflection at an interface from rarer to denser medium, what is the adhoc
change in its phase?

A7: The adhoc change in its phase is π.

Q8: What is the phase difference between two points on the same wavefront?

A8: Phase difference between two points on the same wavefront is zero.

Q9: Define wavefront.

A9: Continuous locus of all the particles of a medium vibrating in the same phase is called wavefront.

Q10: What is interference of light waves?

A10: When two light waves of same frequency travel simultaneously in the same direction then, due to their superposition, the resultant intensity of light at any point in space is different from the sum of intensities of the two waves. At some points the resultant intensity is maximum while at some other points it is minimum (nearly darkness). The re-distribution of light intensity due to the superposition of two light waves is called ‘interference of light’. The interference is said to be ‘constructive’ at points where the resultant intensity is maximum and ‘destructive’ at points where the resultant intensity is minimum or zero
