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