Concave Mirror Image Formation

The video tutorial introduces the concept of image formation using a concave mirror. It begins with an overview of the objectives and proceeds to demonstrate the setup and drawing required for understanding image formation. The tutorial explains the rules governing how images are formed, including the behavior of light rays and the characteristics of the resulting image. The video concludes with a summary of the key points and encourages viewers to engage with the content.

What is the main topic discussed in the video?

• Formation of images by concave mirrors

• Formation of images by convex mirrors

• Formation of images by lenses

• Formation of images by plane mirrors

What is the first step in drawing the concave mirror?

• Drawing the principal axis

• Marking the center of curvature

• Drawing the mirror

• Marking the principal focus

Which point is marked as the center of curvature?

• The point equidistant from the mirror and the principal focus

• The midpoint of the mirror

• The point where the principal axis meets the mirror

• The point at the edge of the mirror

What happens to a ray that passes through the principal focus?

• It reflects at an angle equal to the angle of incidence

• It reflects parallel to the principal axis

• It reflects back through the center of curvature

• It reflects back through the principal focus

What is the rule for a ray passing through the center of curvature?

• It reflects at an angle equal to the angle of incidence

• It reflects back through the principal focus

• It reflects parallel to the principal axis

• It reflects back along the same path

How do you locate the image formed by the concave mirror?

• By observing the mirror directly

• By drawing the reflected rays and finding their intersection

• By using a lens formula

• By measuring the distance from the mirror

Where do the reflected rays intersect to form the image?

• At the principal focus

• At the edge of the mirror

• At the center of curvature

• On the principal axis

What is the nature of the image formed at the center of curvature?

• Real and erect

• Virtual and inverted

• Real and inverted

• Virtual and erect

What is the size of the image formed at the center of curvature compared to the object?

• Same size

• Larger

• Cannot be determined

• Smaller
