Is the second image correct depiction of the path?

Question 4 :
What type of image will form by a convex lens, when an object is placed at infinity.

Question 5 :
What type of image will form by a concave lens, when an object is placed between focus and twice the focal length of the lens.

Question 6 :
The image of a candle flame formed by a lens is obtained on a screen placed on the other side of the lens. If the image is three times the size of the flame and the distance between lens and image is 80 cm, at what distance should the candle be placed from the lens?

Question 7 :
Identify the device used as a spherical mirror or lens in the given case. When the image formed is virtual and erect in this case. CASE: Object is placed between infinity and device, image formed is diminished and between pole and focus, behind it.

Question 8 :

Question 12 :
Where will the image form by a concave lens, when an object is placed beyond twice the focal length of the lens.

Question 13 :
Identify the device used as a spherical mirror or lens in the given case. When the image formed is virtual and erect in this case. CASE: Object is placed between infinity and device, image formed is diminished and between pole and focus, behind it.

Question 14 :
Where will the image form by a convex lens, when an object is placed between optical centre and focus of the lens.

Question 15 :
A child is standing in front of a magic mirror. She finds the image of her head bigger, the middle portion of her body of the same size and that of the legs smaller. The following is the order of combinations for the magic mirror from the top.
