Optics & Wave Optics JEE

Optics is a very important unit both in terms of weightage and concepts. It is very important to learn the various phenomena of light. In ray optics, conditions of mirrors and lens are important to know and in wave optics, it is interference, diffraction, and polarization. With 36 questions between 2009 and 2020, you can expect 3 to 4 questions from this unit every year.

Q.

Fig. shows a wavefront P passing through two systems A and B, and emerging as Q and then as R. The systems A and B could, respectively, be

                                                       

Q.

For the situations shown in the figure, determine the angle by which the mirror should be rotated, so that the light ray will retrace its path after refraction through the prism and reflection from the mirror?

                                              

Q.

A point object is placed in front of a thick plane mirror as shown in figure below. Find the location of final image w.r.t. object.

                                                         

Q.

In the adjacent figure, the fringe width is given by, (here  is the wavelength of incident wave).

                                         

Q.

following diffraction pattern was obtained using a diffraction grating using two different wavelength  With the help of the figure identify which is the longer wavelength and their rations.

                                                 

 

Q. is Ncert enough for Ray Optics JEE main?

NCERT will help you solve just 30% of questions from Optics in JEE the questions in JEE main are more advance and require knowledge of the topic more than what NCERT has to offer so to get a good rank NCERT is not enough.

Q. Is optics difficult for JEE?

Optics requires a lot of virtualization of real-life concepts. It is a practical topic but observation is required. You have been given an introduction to optics mirrors and refractions since class 6 if your concepts are clear you should not face any problems and if you are still facing problems we will advise you to use our video lectures to improve your concepts in optics.

Q. Is human eye questions asked in JEE?

Yes, questions from Human eyes are asked in JEE main and advance. Not the biological part but only the image formation part is there in the syllabus.

Q. Is ray Optics important for JEE?

Yes, it is an important topic for JEE every year around 3 to 4 questions are asked from optics in JEE. Even from the 12th board point of view, it is an important topic.

Q. How many questions are asked from Optics in JEE?

Every year 3 to 4 questions are asked from optics in JEE both in main as well as advance since 2009 36 questions have been asked from optics in JEE.

Q. Can I skip Optics for JEE?

No, we will not advise you to skip but if there is a shortage of time will advise you to do wave optics, interference, diffraction and polarization.

Q. Any Questions from optical Instrument asked in JEE?

We have seen questions from optical Instrument in JEE main but advance has not given any questions from the topic so if you are preparing for advance you can skip it but will have to do it for JEE main.
