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 $
In spectrum X-rays has minimum wavelength and microwave has maximum wavelength.
