If ${\mathrm{\lambda }}_{\mathrm{v}}, {\mathrm{\lambda }}_{\mathrm{x}}\text{ and }{\mathrm{\lambda }}_{\mathrm{m}}$ represent the wavelengths of visible light, X-rays and microwaves, respectively, then

• A

  ${\mathrm{\lambda }}_{\mathrm{m}} > {\mathrm{\lambda }}_{\mathrm{x}} > {\mathrm{\lambda }}_{\mathrm{v}}$

• B

  ${\mathrm{\lambda }}_{\mathrm{v}} > {\mathrm{\lambda }}_{\mathrm{m}} > {\mathrm{\lambda }}_{\mathrm{x}}$

• C

  ${\mathrm{\lambda }}_{\mathrm{m}} > {\mathrm{\lambda }}_{\mathrm{v}} > {\mathrm{\lambda }}_{\mathrm{x}}$

• D

  ${\mathrm{\lambda }}_{\mathrm{v}} > {\mathrm{\lambda }}_{\mathrm{x}} > {\mathrm{\lambda }}_{\mathrm{m}}$
