Question

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

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

Answer 1

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

${\lambda }_m>{\lambda }_v>{\lambda }_x$.
In the given question, $X$-rays have minimum wavelength and microwaves have maximum wavelength.
