Hmm-of-the-Day

Ok, I think many of you would know this by now.. But ANYWAY, today, I'm going to talk about the things above us...

The Sky is blue...
This is due to Rayleigh scattering of the small particles of gas in the atmosphere. This gives the sky a blue appearance.

At Sunrise and Sunset...
Also due to Rayleigh scattering. The sun is low in the horizon and light has to pass through a denser layer of atmosphere whereby more blue light is scattered, leaving the reddish wavelength to reach our eyes.

Clouds...
Due to Tyndall scattering whereby with this phenomenon, the size particles are larger and affects all wavelengths equally... Hence, they're white!


The first sound of thunder occured at 3pm (the start of mass) soon accompanied by rain. It always rains during the Good Friday mass! The rain stopped after mass so I could cycle back home in dry-comfort!
