if `lamda_(v'),lamda_(x)` and `lamda_(m)` represent the wavelengths of visible light X-rays and microwaves respectively then:

Options

A. `lamda_(m)gtlamda_(x)gtlamda_(y)`
B. `lamda_(y)gtlamda_(m)gtlamda_(x)`
C. `lamda_(m)gtlamda_(y)gtlamda_(x)`
D. `lamda_(y)gtlamda_(x)gtlamda_(m)`

Answer

C

Explanation

Wavelength order of given rays are listed below:
`{:("Rays","Wavlength"),("X-rays",1-100),("Microwaves",10^(7)-10_(9)):}`
Obviously `lamda_(x) lt lamda_(v)gtlamda_(x)`
`lamda_(m) lt lamda_(v)gt lamda_(x)`
Note : Visible light X-rays rays and microwaves are all electromagnetic waves.
