Question

Choose the correct option relating wavelengths

• A. ${\lambda }_{radiowaves}>{\lambda }_{microwaves}>{\lambda }_{visible}>{\lambda }_{x-rays}$
• B. ${\lambda }_{visible}>{\lambda }_{x-rays}>{\lambda }_{radiowaves}>{\lambda }_{microwaves}$
• C. ${\lambda }_{visible}<{\lambda }_{microwaves}<{\lambda }_{radiowaves}<{\lambda }_{x-rays}$
• D. ${\lambda }_{x-rays}<{\lambda }_{microwaves}<{\lambda }_{radiowaves}<{\lambda }_{visible}$

Answer 1

The correct option is A

${\lambda }_{radiowaves}>{\lambda }_{microwaves}>{\lambda }_{visible}>{\lambda }_{x-rays}$

We have to choose the correct option by relating wavelength,

We can understand from the figure that wavelength decreases from Radio Waves to Gamma Rays.

Hence, option A ${\lambda }_{radiowaves}>{\lambda }_{microwaves}>{\lambda }_{visible}>{\lambda }_{x-rays}$ is correct.
