a concave mirror has d form f a hemisphere wit d radii 60 cm.a thin layer f an unknown transparent liquid is poured into d mirror. the mirror liquid system forms 1 real image and another real image is formed by mirror alone,,with d source in a certain position.one f dem coincides with the source and d odr is at d distance f L=30 cm from source.find the possible value(s) refractive index of d liquid?????
