Match List I and List II List I List II A Microwaves I Physiotherapy B UV rays II Treatment of cancer C Infra-red rays III Lasik eye surgery D X-rays IV Aircraft navigation Choose the correct answer from the option given below:
Show answer and solution
Answer: (C) A-IV, B-III, C-I, D-II
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. -ray II
Radiation therapy uses high-energy particles or waves, such as x-rays to destroy or damage cancer cells.
