Q. Consider the following electromagnetic radiations with their associated frequencies:
  1. Infra-red
  2. Microwave
  3. Ultra-violet
What is the correct relationship among them regarding frequencies?
Answer: Microwave > Ultra-violet > Infra-red
Notes: Waves of infrared radiation are longer than those of visible light, with frequencies ranging from about 3 gigahertz to about 400 terahertz. Microwaves have frequencies ranging from about 1 gigahertz to about 300 gigahertz. Ultraviolet light falls in the range of the electromagnetic spectrum between visible light and X-rays and has frequencies of about 8 × 1014 to 3 × 1016 cycles per second.
