(a)
(i) Microwave is also used in satellite communications. So, $\lambda_1$ is the wavelength of microwave and it is used in microwave oven.
(ii) Ultraviolet rays are used to kill germs in water purifier. So, $\lambda_2$ is the wavelength of UV rays.
(iii) X-rays are used to detect leakage of oil in underground pipelines. So, $\lambda_3$ is the wavelength of $\mathrm{X}$-rays region. It is used to detect fracture of bones in body.
(iv) Infrared rays $\lambda_4$ is used to improve visibility on runways during fog and mist conditions. So, the wavelength of infrared waves is larger of low scattering.
(b) The arrangement of wavelength in assending order are :
(c) The application all the above equipment are
(i) Microwave is used in radar.
(ii) UV is used in LASER eye surgery.
(iii) $X$-ray is used in radio therapy to cure untracable skin diseases and malignant growths.
(iv) Infrared is used in optical communication.
