Answer:
Hence, both the spherical mirror and the thin spherical lens are concave in nature
Answer:
A spherical mirror and a thin spherical lens have each a focal length of -15 cm. ... For converging lenses, the focal length is always positive, while diverging lenses always have negative focal lengths. Here the answer is both concave. Both the concave mirror and concave lens have a negative focal length
