Identify the electromagnetic waves whose wavelengths lie in the range: (a) 10⁻¹¹m < λ < 10⁻¹⁴m (b) 10⁻⁸m < λ < 10⁻³m. Write one use of each.

The range of wavelength of gamma rays is typically 10⁻¹¹m to 10⁻¹⁴m and the wavelength range of infrared is 10⁻⁸m to 10⁻³m. The gamma rays are used to treat some types of cancer, since the rays also kill cancer cells. The infrared is used in heat sensitive thermal imaging cameras. It can be used to study human and animal body heat patterns.
