Since, lens is made of two layers of different refractive indices, for a given wavelength of light it will have two focal lengths or will form two images at two different points as there are

μ

's as

\frac{1}{f} \propto (μ - 1)

Continuous image is formed between focal points of upper and lower lens

One image is formed

None of the above
