Dear student,
Assertion is True, This is because we know that, by chainging the material the refractive index of the lens changes , which further changes its focal length and using lens formula we can say that the position of image will be changed if focal length of the lens changes.
Hence , using two different material in making the lens can give us two images for the same object.
Reason is False. This is because we know very well that converging lens which converges the incident rays falling on the lens can form real and virtual images both, it is a similar case to that of concave mirror for the nature of images formed
Regards.
