QUESTION
The waves used in common TV remote control are?
OPTIONS
(A) X-Rays
(B) Ultra-violet Rays
(C) Infrared Rays

ANSWER
(C) Infrared Rays
EXPLANATION
Most common television remote controls transmit commands using infrared radiation, typically from an infrared LED to a receiver on the television. X-rays and gamma rays are ionizing radiation and are unsuitable for this purpose, while ultraviolet radiation is not the standard technology used in TV remotes. Hence, option (C), infrared rays, is correct.
