Concave Mirror Image Formation

The video tutorial discusses the conditions under which a concave mirror forms an image, focusing on object placement and its impact on image height. It explains the use of ray diagrams and focal length in understanding image formation. The tutorial also highlights the importance of accurate measurements in achieving correct image representation and concludes with a discussion on the correct answer to a posed question.

Under which condition does a concave mirror produce an image with a height greater than the object?

• When the object is placed at the center of curvature

• When the object is placed between the focus and the mirror

• When the object is placed at the focus

• When the object is placed beyond the center of curvature

What happens to the image when an object is placed at the center of curvature of a concave mirror?

• The image is formed at the focus

• The image is formed at the center of curvature

• The image is formed beyond the center of curvature

• The image is formed between the focus and the mirror

Where should an object be placed to get an enlarged image using a concave mirror?

• Beyond the center of curvature

• At the center of curvature

• Between the focus and the mirror

• At the focus

What is the result of placing an object between the focus and the center of curvature in a concave mirror?

• The image is virtual and inverted

• The image is real and erect

• The image is real and inverted

• The image is virtual and erect

Which path does the secondary ray take in a concave mirror?

• It passes parallel to the principal axis

• It passes through the center of curvature

• It passes through the focal point

• It reflects back on itself

What is the effect of incorrect measurements on the image formed by a concave mirror?

• The image becomes virtual

• The image size remains unchanged

• The image becomes distorted

• The image becomes clearer
