- Statement 1 is correct. In a compound microscope, the objective lens typically has a very short focal length to produce a highly magnified intermediate image. The eyepiece lens acts as a magnifying glass for this intermediate image and usually has a longer focal length than the objective. - Statement 2 is incorrect. The focal length of the eyepiece is typically larger than that of the objective. - Statement 3 is incorrect. The final image produced by a compound microscope and viewed by the observer is a virtual image. The objective lens forms a real intermediate image, but the eyepiece forms a virtual image of this intermediate image. - Statement 4 is correct. The final image observed through the eyepiece of a compound microscope is virtual, magnified, and inverted relative to the original object.
In case of a compound microscope which of the following statements is / are correct? 1. The focal length of the eye piece is larger than the focal length of the objective 2. The focal length of the eye piece is smaller than the focal length of the objective 3. The image produced in a normal optical microscope is real 4. The image produced in a normal optical microscope is virtual Select the correct answer using the code given below:
