Spherical Mirrors

What are the two types of spherical mirrors?

• Square and Circular

• Transparent and Opaque

• Flat and Curved

• Concave and Convex

Draw a ray diagram for a concave mirror when the object is placed beyond the focal point.

• Ray diagram shows the reflected rays from the concave mirror intersecting at the focal point to form a real and inverted image.

• Ray diagram shows the reflected rays from the concave mirror intersecting at the focal point to form a virtual and upright image.

• Ray diagram shows the reflected rays from the concave mirror diverging away from each other to form a virtual and upright image.

• Ray diagram shows the reflected rays from the concave mirror intersecting at a point beyond the focal point to form a real and inverted image.

Explain how an image is formed by a convex mirror.

• An image is formed by a convex mirror through real rays that appear to diverge from a focal point behind the mirror.

• An image is formed by a convex mirror through real rays converging at a focal point in front of the mirror.

• An image is formed by a convex mirror through virtual rays that appear to diverge from a focal point behind the mirror.

• An image is formed by a convex mirror through virtual rays that appear to converge at a focal point behind the mirror.

What are the characteristics of a concave mirror?

• Converging light rays, inverted images, focal point behind the mirror

• Converging light rays, real or virtual images, focal point in front of the mirror

• Diverging light rays, virtual images, focal point behind the mirror

• Parallel light rays, real images, focal point in the mirror

How does a convex mirror differ from a concave mirror in terms of image formation?

• Convex mirror forms virtual, erect, and diminished images; concave mirror forms real and virtual images.

• Convex mirror forms virtual, inverted, and magnified images; concave mirror forms real and erect images.

• Convex mirror forms real, erect, and magnified images; concave mirror forms virtual and diminished images.

• Convex mirror forms real, inverted, and magnified images; concave mirror forms virtual and erect images.

Define the focal length of a concave mirror.

• The focal length of a concave mirror is the distance between the mirror's focal point and the mirror itself.

• The focal length of a concave mirror is the distance between the mirror's vertex and the mirror itself.

• The focal length of a concave mirror is the distance between the mirror's center and the mirror itself.

• The focal length of a concave mirror is the distance between the mirror's focus and the mirror itself.

Describe the characteristics of a convex mirror.

• A convex mirror is flat and reflects light in a focused manner.

• A convex mirror converges light rays and forms real images.

• A convex mirror has a concave shape and always produces inverted images.

• A convex mirror is curved outwards, diverges light rays, forms virtual images, has a focal point behind the mirror, and always produces virtual images.

When an object is placed at the center of curvature of a concave mirror, what type of image is formed?

• Virtual and inverted image

• Real and inverted image

• Real and upright image

• Virtual and upright image

Explain the concept of a virtual image in the context of spherical mirrors.

• A virtual image can be projected onto a screen as the rays actually converge.

• A virtual image is formed when light rays diverge after reflection from a mirror. It cannot be projected onto a screen as the rays do not actually converge.

• A virtual image is always smaller in size compared to the object.

• A virtual image is formed when light rays converge after reflection from a mirror.

How does the size of the image formed by a convex mirror compare to the size of the object?

• The size of the image is smaller than the size of the object.

• The size of the image is equal to the size of the object.

• The size of the image is distorted compared to the size of the object.

• The size of the image is larger than the size of the object.
