Activity 10.4 Class 10 Science

    ·     Draw a neat ray diagram for each position of the object shown in table 10.1.

    ·     You may take any two of the rays mentioned in the previous section for locating the image.

   ·     Compare your diagram with those given in figure 10.7.

   ·     Describe the nature, position, and relative size of the image formed in each case.

    ·     Tabulate the results in a convenient format.

Explanation of activity 10.4 Class 10 Science

We have six positions of objects in front of a concave mirror. To draw the ray diagram for image formation we choose any two rays.

Rule to draw a ray diagram

i.              An incident ray coming parallel to the principal axis passes through focus after reflection.

ii.           A ray of light passing through the centre of curvature of the concave mirror returns to the same path.

iii.        A ray passing through Focus point (F) becomes parallel to the principal axis.

(a)        Beyond C - When we keep a bright object (a burning candle) beyond C and move the paper screen back and forth to get a sharp image of the candle flame on the screen.

Nature of image - Real and inverted

Position of the image – Between F and C

Size of image – smaller than the object

(b)       At C – now the object is placed at C before the concave mirror

Nature of image - Real and inverted

Position of the image – At  C

Size of image – same size as the object

(c)        Between C and F - now the object is placed between F and C

Nature of image - Real and inverted

Position of image – beyond C

Size of image – bigger than the object

(d)       At F - The object is placed at focus point (F)

Nature of image - Real and inverted

Position of image – At infinity

Size of image – Bigger than the object

(e)        Between F and P – Now the object is placed between F and P

Nature of image – Virtual and erect

Position of image – image is formed behind the mirror

Size of image – bigger than the object

Conclusion of activity 10.4 class 10 science

This activity 10.4 explains all the characteristics of the image formed by a concave mirror when an object is placed at different positions in front of the concave mirror.
