Options
- AA-II, B-IV, C-III, D-I
- BA-IV, B-I, C-II, D-III
- CA-IV, B-III, C-I, D-II
- DA-III, B-II, C-I, D-IV
Correct answer
C. A-IV, B-III, C-I, D-II
Step-by-step solution
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. X -ray → II Radiation therapy uses high-energy p
