An equiconvex lens of focal length F is cut in to two equal parts along the vertical axis. The focal length of each part will be

When a beam of white light is allowed to pass through convex lens parallel to principle axis, the different colors of light converge at different point on the principle axis after refraction. This is called

A convex lens of focal length $\frac{1}{3} \text{ m}$ forms a real, inverted image twice the size of the object. The distance of the object from the lens is

Two thin lenses having $\text{R}_1, \text{R}_2$ as the radii of curved surfaces are kept coaxially together. Their power is proportional to}

A convex lens of focal length $\frac{1}{3} \text{ m}$ forms a real, inverted image twice the size of the object. The distance of the object from the lens is

Refractive index of a glass convex lens is $1.5$. The radius of curvature of each of the two surfaces of the lens is $20 \text{ cm}$. The ratio of the power of the lens when immersed in a liquid of refractive index $1.25$ to that when placed in air is

The radii of curvature of both the surfaces of a convex lens of focal length $f$ and focal power $P$ are equal. One of the surfaces is made plane by grinding. The new focal length and focal power of the lens is respectively

A convex lens of focal length 'F' produces a real image 'n' times the size of the object. The image distance is
