HOW DOES HEAT PASS THROUGH GLASS? - PHYSICS STACK EXCHANGE
Mar 1, 2014 How does heat pass through glass? It is not heat that passes through the glass,but electromagnetic radiation in the infrared range, in the same way as the visible light passes. Glass is transparent to visible light and to most of the spectrum before and after visible light frequencies , depending on the optical properties of the specific glass. So infra-red and ultra-violet waves … From physics.stackexchange.com
WHY DOES THE SUN ALWAYS RISE IN THE EAST? - PHYSICS STACK …
Nov 26, 2014 The Sun does not rise, it is the horizon that goes down. You say that Sun rises in the East (with a certain degree of oscillations due to the tilt of the axis) just because the Earth spins from West to East. The revolution affects the difference between sidereal time and solar time, and makes the solar day ≈ 4 ≈ 4 minutes longer If the Earth spinned in the opposite … From physics.stackexchange.com
