Which effect arises in early refracting telescopes due to the lens dispersive properties?

💡 Explanation

When white light passes through a lens, chromatic aberration occurs because different wavelengths refract at slightly different angles, leading to colored fringes around objects. Therefore chromatic aberration results, rather than spherical aberration, coma, or astigmatism which arise from lens shape inaccuracies or off-axis effects.
