Question 10.

Solve the following examples.

5 cm high object is placed at a distance of 25 cm from a converging lens of focal length of 10 cm. Determine the position, size and type of the image.


Answer:

As per the given information


Height of the object is 5 cms


Focal length f is 10 cms


Object distance u = 25 cms


Image distance v= ?


Height of the image h = ?


⇒ 


⇒ 


⇒ 



V = 50/3 =16.66 cms


The image formed will be real and inverted on the other side of the lens at a distance of 16.66 cms from its optical centre.


Now


m= v/u



Where h2 is the height of the object




⇒ h2 = 3.33cms


Therefore from above we can conclude an inverted image of 3.33cm will be formed.
