which describes amaras mistake?\nshe should have drawn a concave lens instead of a convex lens.\nshe should have drawn the image right - side up instead of upside down.\nray 2 should cross through the focal point on the right side of the lens.\nray 3 should point at a downward angle after passing through the lens.

which describes amaras mistake?\nshe should have drawn a concave lens instead of a convex lens.\nshe should have drawn the image right - side up instead of upside down.\nray 2 should cross through the focal point on the right side of the lens.\nray 3 should point at a downward angle after passing through the lens.

Answer

Explanation:

Step1: Recall ray - tracing rules for convex lens

For a convex lens, a ray parallel to the principal axis (ray 2) passes through the focal point on the other side of the lens. In the given diagram, ray 2 is drawn incorrectly as it does not pass through the focal point on the right - hand side of the lens.

Step2: Analyze other options

A convex lens is correctly chosen as per the problem context, so the first option is wrong. For a real image formed by a convex lens, the image is inverted, so the second option is wrong. Ray 3 which passes through the optical center of the lens should go straight without changing direction, so the fourth option is wrong.

Answer:

Ray 2 should cross through the focal point on the right side of the lens.
