Ray Diagrams by Concave and Convex Mirror

Explain the difference between concave and convex mirrors in terms of their shape.

• Concave mirrors are used in makeup, while convex mirrors are used in telescopes.

• Concave mirrors are flat, while convex mirrors are spherical.

• Concave mirrors reflect light outward, while convex mirrors reflect light inward.

• Concave mirrors are curved inward, while convex mirrors are curved outward.

Draw a ray diagram for an object placed between the focal point and the mirror surface of a concave mirror.

• The ray diagram will show two reflected rays diverging from the object (O) towards the focal point (F).

• The ray diagram will show two reflected rays parallel to the principal axis.

• The ray diagram will show two reflected rays converging at the focal point (F) on the same side as the object (O).

• The ray diagram will show two reflected rays diverging from the focal point (F) on the same side as the object (O).

What type of image is formed by a concave mirror when the object is placed beyond the center of curvature?

• Real and inverted

• Real and upright

• Virtual and upright

• Virtual and inverted

Describe how the image formed by a convex mirror differs from that of a concave mirror.

• The image formed by a convex mirror is virtual, upright, and diminished, while the image formed by a concave mirror can be real or virtual, upright or inverted, and magnified or diminished depending on the object's position relative to the focal point.

• The image formed by a convex mirror is real, upright, and magnified.

• The image formed by a convex mirror is virtual, inverted, and magnified.

• The image formed by a convex mirror is real, inverted, and magnified.

Explain the concept of the principal focus of a concave mirror.

• The principal focus of a concave mirror is the point where light rays scatter in all directions

• The principal focus of a concave mirror is the point where light rays pass through without any reflection

• The principal focus of a concave mirror is the point where parallel rays of light converge or appear to diverge from after reflecting off the mirror.

• The principal focus of a concave mirror is the point where rays of light do not interact with the mirror

Draw a ray diagram for an object placed at the center of curvature of a convex mirror.

• The ray diagram will show two reflected rays converging at the focal point behind the mirror.

• The ray diagram will show two reflected rays parallel to the principal axis.

• The ray diagram will show two reflected rays diverging from the focal point behind the mirror.

• The ray diagram will show two reflected rays passing through the center of curvature.

What happens to the image formed by a concave mirror when the object is placed at the focal point?

• A virtual and erect image is formed

• The image is formed at infinity

• A real and inverted image is formed

• No image is formed

Compare the focal length of a concave mirror with that of a convex mirror.

• The focal length of a concave mirror is zero, while the focal length of a convex mirror is infinite.

• The focal length of a concave mirror is negative, while the focal length of a convex mirror is positive.

• The focal length of a concave mirror is shorter than that of a convex mirror.

• The focal length of a concave mirror is positive, while the focal length of a convex mirror is negative.

Describe the nature of the image formed by a convex mirror for different object positions.

• The image formed by a convex mirror is always virtual, inverted, and magnified for different object positions.

• The image formed by a convex mirror is always real, upright, and magnified for different object positions.

• The image formed by a convex mirror is always virtual, upright, and diminished for different object positions.

• The image formed by a convex mirror is always real, inverted, and magnified for different object positions.

How does the size of the image formed by a concave mirror change with the object distance from the mirror?

• The size of the image formed by a concave mirror is not affected by the object distance from the mirror.

• The size of the image formed by a concave mirror decreases as the object distance from the mirror increases.

• The size of the image formed by a concave mirror remains constant regardless of the object distance from the mirror.

• The size of the image formed by a concave mirror increases as the object distance from the mirror increases.
