How does the power of a convex lens vary, if the incident red light is replaced by violet light?
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.

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.
