The power of a convex lens increases when red light is replaced by violet light. This is because violet light has a shorter wavelength, resulting in greater refraction and a smaller focal length, thereby increasing the lens's power.

The biconvex lens will become invisible when placed in a liquid with the same refractive index. This happens because there is no refraction or bending of light at the lens-liquid interface, making the lens indistinguishable.

The biconvex lens will become invisible when placed in a liquid with the same refractive index. This happens because there is no refraction or bending of light at the lens-liquid interface, making the lens indistinguishable.
In a liquid medium with the same refractive index as the lens (1.5), the focal length of the converging lens becomes infinite. This is because there is no refraction at the lens-liquid interface, preventing convergence of light rays. For more visit here: https://www.tiwariacademy.com/ncert-solutionsRead more
In a liquid medium with the same refractive index as the lens (1.5), the focal length of the converging lens becomes infinite. This is because there is no refraction at the lens-liquid interface, preventing convergence of light rays.
The refractive index of the liquid is 1.45. When the glass lens disappears in the liquid, it indicates that the refractive indices of both the lens and the liquid are the same, causing no refraction at the interface.

A convex lens forms a virtual image only when the object is within its focal length. The image is upright, magnified, and on the same side as the object. A concave lens always forms a virtual image, which is upright, diminished, and on the same side. For more visit here: https://www.tiwariacademy.coRead more

How would a biconvex lens appear when placed in a trough of liquid having the same refractive index as that of lens?
The biconvex lens will become invisible when placed in a liquid with the same refractive index. This happens because there is no refraction or bending of light at the lens-liquid interface, making the lens indistinguishable.

A converging lens of refractive index 1.5 is kept in a liquid medium having same refractive index. What would be the focal length of the lens in this medium?
In a liquid medium with the same refractive index as the lens (1.5), the focal length of the converging lens becomes infinite. This is because there is no refraction at the lens-liquid interface, preventing convergence of light rays. For more visit here: https://www.tiwariacademy.com/ncert-solutionsRead more

A glass lens of refractive index 1.45 disappears when immersed in a liquid. What is the value of refractive index of the liquid?
The refractive index of the liquid is 1.45. When the glass lens disappears in the liquid, it indicates that the refractive indices of both the lens and the liquid are the same, causing no refraction at the interface.
