Question

If ${\lambda }_v,{\lambda }_x$ and ${\lambda }_m$ represent the wavelengths of visible light, x-rays and microwaves respectively, then-

• A. ${\lambda }_m>{\lambda }_x>{\lambda }_v$
• B. ${\lambda }_v>{\lambda }_m>{\lambda }_x$
• C. ${\lambda }_v>{\lambda }_x>{\lambda }_m$
• D. ${\lambda }_m>{\lambda }_v>{\lambda }_x$

Answer 1

The correct option is D ${\lambda }_m>{\lambda }_v>{\lambda }_x$

Given that,

${\lambda }_v=$ Wavelength of visible light

${\lambda }_x=$ Wavelength of $X-$ rays

${\lambda }_m=$ Wavelength of microwaves.

$\therefore {\lambda }_m>{\lambda }_v>{\lambda }_x$
