Which behavior is not true for incident rays striking a concave mirror? a. incident rays parallel to the principal axis are reflected to the focus
b. incident rays passing through the focus are reflected parallel to the principal axis
c. incident rays passing through the center are reflected back to the center.
d. incident rays from an object at infinity and parallel to the principal axis are reflected to the center.

Option (D)

Explanation:

a concave mirror is called a converging mirror, because when the rays of light falls on it, it converges the path of rays of light falling on it after reflection.

When the rays from the object at infinity and parallel to the principal axis, then after reflection they passes form the focus of the mirror.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
