Question

What happens when a beam of sunlight enters a dusty room through the windows? Explain your answer.

Answer 1

Hint: Dusty rooms are caused by a variety of things, but mostly you'll check out mites, mold, and other particles gathering on surfaces. The more surfaces you've got , the more chances the mites need to make homes and make dust. The more cloth surfaces you've got , the more you'll have dust floating around.

Complete answer:
When a beam of sunlight enters a dusty room through a window, then its path appears to us. The small dust particles present within the air of the room scatter the beam of sunshine all round the room.
When a beam of sunlight enters an area , suspended dust particles are seen moving haphazardly. This is often because the dust particles are constantly hit by the fast paced particles of air and thanks to this remain suspended despite gravity working on them.
Yes, the sun can cause dust particles to spread in your house, because the sun's radiation heats the ground and walls. The ground and walls heat the air, causing convection currents. The convection currents lift the dust and carry it into every nook, cranny and corner of your house.
The phenomena exhibited by particle x is understood as the Tyndall effect .

Note: Dust also comes in through windows, doors and cracks around windows and doors. Soil, mold spores, pollen, soot and other bits of the surface find their way inside into your house dust. Like your pets, you carry a number of these in on your hair and skin.
