Characteristics of Images in Mirrors

The video tutorial explains how to fill Table 15.1 by discussing the characteristics of images formed by a concave mirror. It covers the differences between real and virtual images, as well as inverted and erect images. The tutorial also explains the use of the mirror formula to calculate image distance and focal length. Finally, it provides guidance on filling the table based on the characteristics of images formed at different object distances.

What information is required in Table 15.1 regarding the image?

• Size and character of the image

• Color and position of the image

• Position and brightness of the image

• Size and color of the image

How can you determine if an image is real?

• If it is colorful

• If it is smaller than the object

• If it is larger than the object

• If it can be obtained on a screen

What is a characteristic of a virtual image?

• It can be projected on a screen

• It is always inverted

• It is always larger than the object

• It cannot be obtained on a screen

When is an image considered inverted?

• When it is smaller than the object

• When it is larger than the object

• When it is below the principal axis

• When it is above the principal axis

What does an erect image indicate?

• The image is below the principal axis

• The image is above the principal axis

• The image is real

• The image is virtual

What type of mirror is used in the example for Table 15.1?

• Concave mirror

• Plane mirror

• Convex mirror

• Spherical mirror

What happens to the image when the object is placed beyond C and F?

• The image is diminished and virtual

• The image is enlarged, real, and inverted

• The image is the same size and erect

• The image is diminished and real

What is the symbol 'u' used for in the mirror formula?

• Height of the object

• Focal length of the mirror

• Object distance from the mirror

• Image distance from the mirror

What happens to the image characteristics when the object is moved between F and P?

• The image becomes smaller and virtual

• The image becomes smaller and real

• The image becomes highly enlarged and virtual

• The image becomes highly enlarged and real

What is the value of 'v' when the object distance 'u' is 50 cm?

• 50 cm

• -50 cm

• 75 cm

• -75 cm
