Question
(a) First, focus on the concave/converging mirror, which can produce more types of images than the convex mirror or the plane mirror. CHOOSE ALL THE CORRECT STATEMENTS ABOUT CONCAVE MIRRORS FROM THE LIST BELOW.
The concave mirror can produce real images that are larger than, smaller than, or the same size as the object
The concave mirror can produce virtual images that are larger than, smaller than, or the same size as the object
If you move the object toward the concave mirror, the image always gets larger
If you double the height of the object, the image height also doubles
All rays of light that leave the tip of the object and reflect off the mirror pass through the tip of the image (or can be extended back to do so)
Only the three special rays (in red, blue, and green) that leave the tip of the object and reflect off the mirror pass through the tip of the image (or can be extended back to do so)
The object height can only be positive T
he magnification (the ratio of image height to object height) for the concave mirror can only be a negative value
There is only one way to create an image that is two times larger than the object itself
(b) Now, consider these general statements, regarding the three different kinds of mirrors (Plane, Concave/Converging and Convex/Diverging). AGAIN, SELECT ALL THAT APPLY.
The concave mirror only produces real images while the plane and convex mirrors only produce virtual images
If the image is virtual, moving the object closer to the mirror always causes the image to move closer to the mirror
With a convex mirror, the image height can be increased by (i) increasing the object height, (ii) moving the object closer to the mirror, or (iii) increasing the magnitude of the focal length
Keeping the object unchanged, switching from the concave mirror to the convex mirror to the plane mirror will not change the blue ray
The convex mirror always produces an image smaller than the object; the plane mirror produces an image the same size as the object; and the concave mirror always produces an image larger than the object
If you double the height of the object, the image height also doubles
All rays of light that leave the tip of the object and reflect off the mirror pass through the tip of the image (or can be extended back to do so)
PLEASE HELP!!! ANSWER BOTH QUESTIONS COMPLETELY!! :(

CHOOSE ALL THE CORRECT STATEMENTS ABOUT CONCAVE MIRRORS FROM THE LIST BELOW -
1) The concave mirror can produce real images that are larger than, smaller than, or the same size as the object. True. (Larger when object is located between C and F, Smaller when object is located beyond C & same size when object is located at C)
2) The concave mirror can produce virtual images that are larger than, smaller than, or the same size as the object. (False, Virtual Image formed is magnified in size.)
3) If you move the object toward the concave mirror, the image always gets larger. (True, Explanation for case 1 can be used.)
4) If you double the height of the object, the image height also doubles. (True, Height of object is given by, hi = M*ho i.e directly proportional.)
5) All rays of light that leave the tip of the object and reflect off the mirror pass through the tip of the image (or can be extended back to do so) (Flase.)
6) Only the three special rays (in red, blue, and green) that leave the tip of the object and reflect off the mirror pass through the tip of the image (or can be extended back to do so) (True.)
7) The object height can only be positive. (True Height is allways positive.)
8) The magnification (the ratio of image height to object height) for the concave mirror can only be a negative value. (False, It can be Positive in case of Virtual Image as the image is upright.)
9) There is only one way to create an image that is two times larger than the object itself. (False, There are two ways, one the virtual image and second when the object is located between C and F)
