CBSE XII Compartment Exam Physics question paper can be had from the attachment below.
Some question that came for the exam were:
1. Isotones are nuclides having :
(A) same number of neutrons but different number of protons
(B) same number of protons but different number of neutrons
© same number of protons and also same number of neutrons
(D) different number of protons and also different number of neutrons
2. A point object is placed in air at a distance of 4R on the principal axis of a convex spherical surface of radius of curvature R separating two mediums, air and glass. As the object is moved towards the surface, the image formed is :
(A) always real
(B) always virtual
© first virtual and then real
(D) first real and then virtual
3. State Huygens principle. Using it draw a diagram showing the details of passage of a plane wave from a denser into a rarer medium.
4. Explain the following, giving proper reason :
(a) During charging of a capacitor, displacement current exists in the capacitor. But there is no displacement current when it gets fully charged.
(b) The frequency of microwaves in ovens matches with the resonant frequency of water molecules.
© Infrared waves are also known as heat waves.
