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

Answer: (B)

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

Answer 2

${\lambda }_m > {\lambda }_v > {\lambda }_x$
In spectrum X-rays has minimum wavelength and microwave has maximum wavelength.
