Question:
an object 5.0 cm in length is held 25cm away from converging lens of focal length 10 cm draw the ray diagram and find the pasition size and the nature of the images formed ka solution
Answer:
The lens formula relates the object distance (u), the image distance (v), and the focal length (f) of a lens. The formula is:
1/f=1/v−1/u
Substituing the values
(1/10)cm=(1/v)−(1/25)cm
1=(1/10)cm+(1/25)
1/v=(5/50)+(2/50
(1/v)=(50/7)
So, the image distance (v) is approximately 7.14 cm
M=−(v/u)
M=−(7.14 cm/25 cm)
M≈−0.2856
It will be a real image,the image is formed on the same side as the object.
The magnification is negative, showing that the image is inverted.
Therefore, the image is real, inverted, and smaller in size than the object.
