Physics Class 12th

Given below are two statements : one is labeled as Assertion A and the other is labeled as Reason R.

Assertion A : For a simple microscope, the angular size of the object equals the angular size of the image.

Reason R : Magnification is achieved as the small object can be kept much closer to the eye that 25cm and hence it subtends a large angle.

In the light of the above statements, choose the most appropriate answer from the options given below:

a = 1, r = cos2

$x = S_{\infty} = \frac{a}{1 - r} = \frac{1}{1 - c o s^{2} θ} = \frac{1}{s i n^{2} θ}$

Choosing a specialisation is not always easy. Many students later realise they want to study something else. Chandigarh University does provide a way to change specialization, but it works with some conditions.

If you apply before the academic session begins, you can directly approach the admission office. They will ask you to fill out forms, submit documents, and clear any fee difference.

If you are already attending classes, the process is slightly longer. First, you must speak with your HOD and explain your choice. Then the request goes to the higher administration. The final approval will only be given if there are free seats in the
