Explanation:

Justification: The small sized colloidal particles in air can easily scatter a beam of visible light. This scattering of a beam of light is called the Tyndall effect.
Statement 1: In the forest, mist contains tiny droplets of water, which act as particles of colloid dispersed in air.
Statement 2: Dust and smoke present in the air scatter the beam of light.
