MCQ
Which one of the following is more monocromatic?
  • Laser beam
  • B
    White light
  • C
    Sodium light
  • D
    Mercury light

Answer

Correct option: A.
Laser beam

Monochromatic light is light made up of one single pure frequency.white light, which is light that contains all frequencies, That means the sum of red, yellow, green, blue and violet. Some light sources send out monochromatic light such as lasers beam.
