Concave Mirror Image Formation Concepts

The video tutorial explains how to draw ray diagrams for concave mirrors and use them to locate images. It covers key components like the principal axis, center of curvature, and focal point. The tutorial demonstrates different cases based on object placement relative to these points, explaining how to draw ray diagrams and describe the resulting images. It highlights the similarities between concave mirrors and convex lenses, emphasizing the importance of understanding patterns rather than memorizing cases.

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

• A line perpendicular to the mirror surface

• A line parallel to the mirror surface

• A horizontal line through the center of the mirror

• A vertical line through the focal point

Which point is located at the center of the circle in a spherical mirror?

• Center of curvature

• Principal axis

• Vertex

• Focal point

When drawing ray diagrams for concave mirrors, what is the first step?

• Draw a ray perpendicular to the mirror

• Draw a ray through the center of curvature

• Draw a ray parallel to the principal axis

• Draw a ray through the focal point

What happens to the image when the object is placed beyond the center of curvature (C) in a concave mirror?

• The image is virtual and upright

• The image is larger than the object

• The image is at the focal point

• The image is real and inverted

Where is the image located when the object is at the center of curvature (C) in a concave mirror?

• At the focal point

• Beyond the center of curvature

• Inside the focal point

• At the center of curvature

What is the nature of the image when the object is placed between the center of curvature (C) and the focal point (f)?

• Virtual, inverted, and magnified

• Real, inverted, and magnified

• Virtual, upright, and reduced

• Real, upright, and reduced

What occurs when the object is placed at the focal point of a concave mirror?

• A virtual image is formed behind the mirror

• No image is formed

• A magnified image is formed

• A real image is formed at the focal point

How is a virtual image formed in a concave mirror?

• By parallel light rays

• By reflected light rays

• By diverging light rays

• By converging light rays

What is the similarity between concave mirrors and convex lenses?

• Both have the same focal length

• Both create real images only

• Both create virtual images only

• Both are converging devices

What happens to the image as the object moves closer to the focal point in a concave mirror?

• The image becomes smaller and upright

• The image becomes larger and inverted

• The image becomes smaller and inverted

• The image becomes larger and upright
