The focal length of a lens for red light will be more than that for blue light. This is because red light has a longer wavelength, causing it to refract less, resulting in a larger focal length compared to blue light.

A biconvex lens of glass acts as a plane glass sheet when immersed in a liquid with the same refractive index as the glass. In this case, no refraction occurs at the lens-liquid interface, making the lens indistinguishable. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/Read more

When a convex lens is held in water, its focal length increases. Since water has a higher refractive index than air, the refractive power of the lens decreases, resulting in a longer focal length compared to its value in air.

A diamond cutter uses the high refractive index of diamond to create sharp, precise cuts. The greater refractive index causes light to refract more sharply, enhancing brilliance and ensuring the diamond's facets reflect light effectively for maximum sparkle.

The lens will behave as a converging lens. Since the refractive index of water (1.33) is higher than that of the lens material (1.25), light will bend inward, causing the biconcave lens to act as a converging lens.

A convex lens is held in water. What change, if any, do you expect in its focal length?
When a convex lens is held in water, its focal length increases. Since water has a higher refractive index than air, the refractive power of the lens decreases, resulting in a longer focal length compared to its value in air.

A biconcave lens made of a transparent material of refractive index 1.25 is immersed in water of refractive index 1.33. Will the lens behave as a converging or a diverging lens ? Give reason.
The lens will behave as a converging lens. Since the refractive index of water (1.33) is higher than that of the lens material (1.25), light will bend inward, causing the biconcave lens to act as a converging lens.
