The range of wavelengths of the infrared waves in an electromagnetic spectrum is 10−3 m to 10−6m. The wavelength of the radiation is
longer than 10−6m.
shorter than 10−6m.
shorter than 103m.
longer than 103m.
Correct answer is A
The range of wavelengths for infrared waves is given as 10−3 m to 10−6m. This means that the wavelength of the radiation is longer than 10−6m but shorter than \{10^{-3} m\). Therefore, the only correct option is that the wavelength is longer than 10−6m.
