MCQ
An achromatic combination of lenses produce:
  • A
    Images in black and white
  • B
    Colored images
  • Images unaffected by variation of refractive index with wavelength
  • D
    Highly enlarged images

Answer

Correct option: C.
Images unaffected by variation of refractive index with wavelength

An achromatic combination of lenses provide deviation without dispersion. So, images are unaffected by variation of refractive index with wavelength.
