Answer
(a) The student’s claim is correct because the strength of a magnetic field is indicated by how close together the magnetic field lines are. Near point X, which is close to the pole (N) of the magnet, the field lines are closer, so the magnetic field is stronger there and at point Y, the field lines are more spread out, so the field is weaker.
(b) The completed and marked diagram is shown below :

The below image is that of a Digital Single Lense Reflector (DSLR) Camera which are used to take high resolution photographs by professional photographers. The second image of the below two is a schematic diagram of how an image is formed on the sensor of the camera. Based on your understanding of the lenses, answer the following questions.
(a) What type of lens is used in the DSLR camera shown in the image?
(b) What type of image is formed on the sensor?
Attempt either subpart C or D.
(c) A photographer is using a DSLR camera with a lens of focal length f = 50 mm to take a close-up photograph of a small object. The lens projects an image onto the camera sensor that is located 60 mm behind the lens. Calculate the object distance (i.e., the distance between the object and the lens).

(d) A photographer is using a DSLR camera to take a picture of a flower. The flower is positioned 150 mm away from the camera lens. The actual height of the flower is 80 mm, and the image height formed on the camera’s sensor is measured to be 20 mm. Calculate the focal length of the camera lens.
Zarina worked as an apprentice in a factory where flashlights and solar cookers are made. She learnt to make the circuits, the design of the light-box and light concentrators of the solar cookers as well. She learnt the uses of lenses in making all those tools. Based on your understanding of lenses, answer the following questions.
(a) What kind of lenses are used in the flashlight and light concentrator of the solar-cooker?
(b) Give reasons for your choices in your answer for part A.
Attempt either subpart C or D.
(c) An object is placed 40 cm away from a lens which is normally used in a solar-cooker. The image formed is twice the size of the object. Calculate the focal length of the lens.
OR
(d) An object is placed 20 cm in front of a lens which is used in a flashlight, and the image is formed 10 cm away from the lens on the same side as the object. Calculate the focal length of the lens.
