{'concave mirror': [0, 0, 2, 6], 'spherical mirror': [0, 0, 0, 1], 'focal length': [1, 0, 5, 7], 'curvature': [0, 0, 1, 0], 'reflection': [1, 1, 2, 19], 'mirror': [0, 0, 0, 1], 'principal focus': [0, 0, 1, 2], 'denser medium bends': [0, 0, 0, 1], 'infinity': [0, 0, 1, 7], 'principal axis': [0, 0, 1, 1], 'radius': [0, 0, 2, 2], 'ray': [2, 0, 5, 15], 'light': [16, 4, 34, 62]}

Option 1: The statement says that when an object lies at infinity, the image formed by a concave mirror is at the principal focus, highly diminished, real, and inverted. This means that the image is formed at the focal point of the mirror, it is much smaller in size compared to the object, it is a real image that can be projected onto a screen, and it is inverted in orientation.

Option 2: The statement says that a ray of light parallel to the principal axis, after reflection from a concave mirror, appears to diverge from the principal focus of the mirror. This statement is incorrect. According to the laws of reflection, a ray of light parallel to the principal axis, after reflection, passes through the principal focus of a concave mirror. It does not appear to diverge.

Option 3: The statement says that the focal length of a spherical mirror is double its radius of curvature. This statement is incorrect. The focal length of a spherical mirror is half of its radius of curvature, not double.

Option 4: The statement says that a ray of light traveling from a rarer medium to a denser medium bends away from the normal. This statement is incorrect. When light travels from a rarer medium to a denser
