True or False: The image formed by a convex mirror can be larger than the object.
False
Fill in the blank: In a convex mirror, the focal length is always __________.
positive
What is the nature of the image formed by a convex mirror when the object is placed at any distance?

What is the use of convex mirrors in vehicles?
To provide a wider field of view for the driver.
Complete the sentence: The image distance in a convex mirror is __________.
always negative
What happens to the size of the image as the object moves closer to a convex mirror?
The size of the image remains smaller than the object.
True or False: Convex mirrors are used in security applications.
True
What type of lens is a convex mirror classified as?
Diverging mirror
What type of mirror is a concave mirror?
A concave mirror is a spherical mirror that curves inward.
True or False: Concave mirrors can produce both real and virtual images.
True.
What is the focal point of a concave mirror?
The focal point is the point where parallel rays of light converge after reflecting off the mirror.
Fill in the blank: The focal length of a concave mirror is __________.
negative.
What happens to the image when the object is placed beyond the center of curvature (C) in a concave mirror?
The image is real, inverted, and smaller than the object.
What is the nature of the image formed when the object is at the center of curvature (C)?
The image is real, inverted, and of the same size as the object.
What occurs when the object is placed between the focal point (F) and the mirror?
The image is virtual, upright, and larger than the object.
True or False: A concave mirror can only produce real images.
False.
What is the significance of the center of curvature (C) in a concave mirror?
It is the center of the sphere of which the mirror is a part.
If an object is placed at infinity in front of a concave mirror, what type of image is formed?
A real, inverted image at the focal point.
Fill in the blank: The distance from the mirror’s surface to the focal point is called the __________.
focal length.
What image characteristics are observed when the object is placed at the focal point (F)?
The image is formed at infinity and cannot be seen.
