Characteristics and Properties of Mirrors

Miss Leia explains image formation in mirrors, focusing on plane and spherical mirrors, including concave and convex types. She covers key terms for ray diagrams, such as principal axis, focal point, and curvature. The video details reflection rules for concave and convex mirrors, illustrating how images are formed and their characteristics. Practical examples like shaving mirrors and surveillance mirrors are discussed to highlight real-world applications.

What type of image is formed by a plane mirror?

• Inverted and real

• Diminished and virtual

• Upright and virtual

• Enlarged and real

Which of the following is an example of a concave mirror?

• Surveillance mirror

• Shaving mirror

• Rearview mirror

• Bathroom mirror

What is the main characteristic of a convex mirror?

• It bulges towards the object

• It forms real images

• It inverts images

• It magnifies images

What is the principal axis in the context of spherical mirrors?

• The line tangent to the mirror surface

• The line perpendicular to the mirror surface

• The line parallel to the mirror surface

• The line passing through the center of the sphere

What is the focal length of a mirror?

• The distance from the object to the focal point

• The distance from the mirror to the center of curvature

• The distance from the mirror to the focal point

• The distance from the mirror to the object

How is the angle of incidence related to the angle of reflection in concave mirrors?

• They are unrelated

• The angle of reflection is double the angle of incidence

• The angle of incidence is double the angle of reflection

• They are equal

What type of image is formed by a concave mirror when the object is placed between the focal point and the mirror?

• Real and inverted

• Real and upright

• Virtual and inverted

• Virtual and upright

Which of the following is true for images formed by convex mirrors?

• They are always enlarged

• They are always virtual

• They are always inverted

• They are always real

What is the purpose of using arrows in ray diagrams?

• To show the size of the object

• To simplify the diagram

• To indicate the direction of light

• To mark the focal point

Why can't a real image be formed by a convex mirror?

• Because it only forms inverted images

• Because it only forms virtual images

• Because it only refracts light

• Because it only reflects light
