# Which of the Following Quantities Related to a Lens Depend on the Wavelength Or Wavelengths of the Incident Light? (A) Power (B) Focal Length (C) Chromatic Aberration (D) Radii of Curvature - Physics

Short Note

Which of the following quantities related to a lens depend on the wavelength or wavelengths of the incident light?

(a) Power

(b) Focal length

(c) Chromatic aberration

#### Solution

(a) Power

(b) Focal length

(c) Chromatic aberration

The focal length, power and chromatic aberration are dependent on the refractive index of the lens, which itself is dependent on the wavelength of the light.
