Answer 1

Answer:

here are you answer

Explanation:

1.From the observation 3, we can say that Radius of curvature is 40cm so foal length of the convex lens is 20cm.[f=R/2]

2. Observation 6 is incorrect , as the object is in between P and F, the image formed will be virtual image on the same side of object, image distance should be negative.

3.Ray diagram for observation 3: Please refer attachment : object beyond C

4. magnification=m=v/um=30/-60=-1/2= -0.5so the image is real, inverted and diminished.
