The streaming of light beams coming from the Sun through trees is said to have suggested that light travels in straight line. The particles on the path of light beams are visible to us because

Options

  1. Adust particles in the air reflect light into our eyes
  2. Bdust particles· in the air scatter light into our eyes
  3. Cdust particles in the air refract light into our eyes
  4. Ddust particles in the air polarize light into our eyes

Correct answer

B. dust particles· in the air scatter light into our eyes

Step-by-step solution

The scattering of light by colloidal particles like dust, smoke, water droplets etc , This phenomenon s known as tyndall effect . It is seen when a fine beam of sunlight enters a dusty room, Thus, the scattering of light makes the particle visible.
