What is the wavelength of ultraviolet spectrum ?

  • A.0.3 to 0.4 micrometer
  • B.1 to 300 millimeter
  • C.0.4 to 0.7 micrometer
  • D.\(\gt\) 300 centimeter

Answer: A

The ultraviolet wavelength used here is 0.3 to 0.4 micrometer.

In remote sensing, the photographic or near ultraviolet that passes through the atmosphere lies just short of visible light, about 0.3-0.4 micrometres. Shorter UV is absorbed by ozone and does not reach the ground.

0.4 to 0.7 micrometre is the visible band. 1 to 300 millimetre covers microwaves, and more than 300 centimetre lies in the radio region.
