A. Microwave → IV Microwaves have short wavelength hence low energy dispersion during long distance communication. Thus, they are used in radar system. B. UV rays → III LASIK uses an excimer laser (an ultraviolet laser) to remove a thin layer of corneal tissue. C. Infra-red → I Infrared radiation in the device called infrared lamp is used in physiotherapy. This light is useful in reducing pain, decreasing inflammation, and speeding up wound care and tissue repair. D.
