To solve the problem, we need to understand the relationship between the exposure time and the aperture of the camera lens. The exposure time (T) is inversely proportional to the square of the aperture (f-number). ### Step-by-Step Solution: 1. **Identify the given values**: - Initial aperture (A1) = f/2 - Initial exposure time (T1) = 1/100 seconds - New aperture (A2) = f/4 ...

Choose the correct alternative corresponding to the object distance 'u', image distance 'v' and the focal length 'F' of a converging lens from the following . The average speed of the image as the object moves with the uniform speed from distance (3F)/(4) to (F)/(2) is greater than the average speed of the image as the object moves with same speed from distance (F)/(2) "to" (F)/(4) The minimum distance between a real object and its real image in case of a converging lens is 4F where F is its focal length.
