(vi) When objects are viewed through the rising heat of a campfire they appear to shimmer. The optical phenomenon responsible for this effect is: 

(a) refraction 

(b) reflection 

(c) scattering 

(d) total internal reflection 

(vii) A convex lens with a focal length of 12 cm has an object at a distance of 20 cm in front of the lens. A blurred image is obtained on the screen placed at a distance of 23 cm in front of the lens. In order to obtain a clear image, the screen has to be moved: 

(a) towards the lens. 

(b) away from the lens. 

(c) to a position very far from the lens. 

(d) either towards or away from the lens. 

(viii) Assertion(A): Soldiers avoid firing at a target in foggy weather conditions.

Reason(R): In foggy weather, light gets scattered by tiny water droplets, reducing visibility

(b) (A) is false but (R) is true. 

(c) Both (A) and (R) are true and (R) is the correct explanation of (A).

(i) (a) Refer to the diagram given below. A lens is made of two materials of different refractive indices (µ1, µ2) as shown. If the rays are coming from a distant object, then how many images will be seen?

(b) A glass lens always forms a virtual, erect, and diminished image of an object kept in front of it. Identify the lens.

(ii) The image given below displays kilowatt-hour meter readings recorded at two distinct points in time. 

Assuming a continuously running 2000W air conditioner as the sole electrical device in use, calculate the time interval, in hours, between these two meter readings.

(iii) ABCDE is a regular pentagon with its centre of gravity at O. What will be the most probable position (W, X, Y, Z or O) of the new centre of gravity: 

(a) if a piece of clay is attached at point A? 

(b) if the pentagon is cut along the line PQ? (Of the remaining part DCBQPE)

(iv) A solid of mass 60 g at 100°C is placed in 150 g of water at 20°C. The final steady temperature is 25°C. Calculate the heat capacity of the solid. 

(v) The diagram given below shows a copper wire wound around a U-shape soft iron bar. An iron pin is brought near the arrangement. First Source P and then Source Q are connected across AB, each operating independently.

(a) State True or False: Source P as well as Source Q, when connected across AB, can attract the iron pin. 

(b) Justify your answer to (a) with a suitable reason.

(vi) 

(a) Name the radiation that is emitted during the decay of a nucleus that has the highest penetrating power. 

(b) Does the emission of the above-mentioned radiation result in a change in the mass number? 

(vii) Advanced optical sensors in air-to-air missiles use fiber optic cables to transmit light signals with minimal loss. This relies on a physical phenomenon that confines light within the fibers, making the system very dependable for guiding the missile precisely. 

(a) Name the optical phenomenon that allows light signals to remain confined within the fiber optic cables during transmission. 

(b) Explain the two main conditions necessary for this phenomenon to occur.
