Question

Question 6 An object O is placed to the left of a converging lens as shown below. The focal length of the lens is labeled f. The object is more than twice the focal distance away. Which position most closely predicts the location and orientation of the image formed by this lens? (Assume ail lengths are approximately to scale) A B C D E Question 7 Suppose you cover the lower half of the lens with a piece of paper. You will see An image of the part of the object that is above the center line. An image of the part of the object that is below the center line. An image of the entire object, but it will look very fuzzy. An image of the entire object, but it will look fainter. Harry Potter

Explanation / Answer

6) option C is the correct answer

Explanation :

let f = 10 cm

u = 30 cm

v = ?

Apply, 1/u + 1/v = 1/f

1/v = 1/f - 1/u

1/v = 1/10 - 1/30

v = 15 cm

so, image is real,inverted and it is close to focal point in the oether side.

7) D) An image of the entire object, but it will look fainter.

Explanation :

Unsually Image is formed due to all the from object.
But, When the lower half of the lense is closed with paper half the rays are missed.
so the image will not be bright. it becomes fainter.still we can see complete image.
