For which of the two lenses L-1 and L-2 the chromatic aberration will be the dispersive power of the material of L-1 is than that of L-2-L-1L-2L-1-L-2none of the above

Question

Toppr Admin · Accepted Answer

Chromatic aberration of a lens is directly related to its dispersive power that is more the dispersive power, more is chromatic aberration.

Since, dispersive power of $L_{2}$ is more than $L_{1}$ , chromatic aberration will be more in $L_{2}$ .

Answer-(B)

For which of the two lenses L1 and L2 the chromatic aberration will be more if the dispersive power of the material of L1 is less than that of L2:L1L2L1=L2none of the above

Chromatic aberration of a lens is directly related to its dispersive power that is more the dispersive power, more is chromatic aberration.Since, dispersive power of L2 is more than L1, chromatic aberration will be more in L2.Answer-(B)

For which of the two lenses $L_{1}$ and $L_{2}$ the chromatic aberration will be more if the dispersive power of the material of $L_{1}$ is less than that of $L_{2}$ :
$L_{1}$
$L_{2}$
$L_{1} = L_{2}$
none of the above

Chromatic aberration of a lens is directly related to its dispersive power that is more the dispersive power, more is chromatic aberration.

Since, dispersive power of $L_{2}$ is more than $L_{1}$ , chromatic aberration will be more in $L_{2}$ .
