The wave length of light in visible part $\left({\mathrm{\lambda }}_{\mathrm{V}}\right)$ and for sound $\left({\mathrm{\lambda }}_{\mathrm{S}}\right)$ are related as 

• A

  ${\mathrm{\lambda }}_{\mathrm{V}}>{\mathrm{\lambda }}_{\mathrm{S}}$

• B

  ${\mathrm{\lambda }}_{\mathrm{S}}>{\mathrm{\lambda }}_{\mathrm{V}}$

• C

  ${\mathrm{\lambda }}_{\mathrm{S}}={\mathrm{\lambda }}_{\mathrm{V}}$

• D

  None of these
