59 Consider the ray diagrams for a concave mirror focal length fM and a convex lens focal length fr in air as shown in the figure below if What happens to their focal lengths when they are immersed in a medium of refractive index higher than that of air fM A fM changes and fr stays same B fM stays same and fr changes C both fM and fL changes D both fM and fr stay same
