The range of wavelengths of the infrared waves in an electromagnetic spectrum is 103 m  to 106m. The wavelength of the radiation is

A.

longer than 106m.

B.

shorter than 106m.

C.

shorter than 103m.

D.

longer than 103m.

Correct answer is A

The range of wavelengths for infrared waves is given as 103 m  to 106m. This means that the wavelength of the radiation is longer than 106m but shorter than \{10^{-3} m\). Therefore, the only correct option is that the wavelength is longer than 106m.
