A convergent beam of light passes through a diverging lens of focal length 0.2 m and comes to focus 0.3 m behind the lens. Find the position of the point at which the beam would converge in the absence of lens.​
  • a)
    0.1 m
  • b)
    0.22 m
  • c)
    0.2 m
  • d)
    0.12 m
Correct answer is option 'D'. Can you explain this answer?

The image is 0.3 m to the right of the lens. This is 0.5 m TO THE RIGHT OF the left hand (image) focal point. 
As explained above, concave lenses have their focal points on the opposite side of the lens to a convex lens. 

So in the formula so* si = f^2 si = 0.5 
f^2 = 0.2 ^2= 0.04 

Therefore so = 0.04/ 0.5 = 0.08 m 

This means that the object must have been 0.08 m to the left of its focal point. 

which places it at 0.12m from the lens 

This would be the point at which the rays of light would have converged if the lens had not been present. 

It is actually a VIRTUAL OBJECT because the light never actually reaches this point. 
The final point the light reaches is a REAL IMAGE because the light actually does focus at this point as can be seen by putting a paper screen there.

Given:
f = -0.2 m (since the lens is diverging)
u = ?
v = 0.3 m

Using the lens formula,
1/f = 1/v - 1/u
Substituting the given values,
1/-0.2 = 1/0.3 - 1/u
Simplifying,
-5 = 3/u
u = -0.6 m

The negative sign indicates that the light is incident on the lens from the other side. To find the position of the point at which the beam would converge in the absence of lens, we need to consider only the magnitude of u which is 0.6 m.

Therefore, the answer is option 'D' 0.12 m.
