Which one of the following statements is correct? Wavelength of microwaves ranges between
General SciencePhysics
- Ainfrared waves and radio waves.
- Bvisible waves and infrared light.
- Cy-rays and X-rays.
- DX-rays and visible waves.
Explanation
In the electromagnetic spectrum, wavelength increases from gamma rays through X-rays, ultraviolet, visible light, infrared, microwaves, to radio waves. Microwaves (roughly 1 mm to 1 m) therefore lie between infrared waves and radio waves. Hence (A) is correct.
