In winter, its warmer to bask in the glass. Why? Because the glass of solar radiation light almost completely through, and the room temperature indoor objects because ordinary glass of solar radiation light almost completely penetrating infrared radiation barrier in north room, late autumn or early winter morning, 2. north, late autumn or early winter morning, morning season why leaves are always in the direction the space side frosting? Frost? Because the back side and space compared to the leaves toward the side of space and space radiation back into space because more side compared to the heat, the temperature is lower, the surface of the heat, the temperature is lower on the surface, so it is more easily frosting at room temperature is the black iron bar is heated in a furnace at the color is dark, gradually, the 3. The black bar at room temperature is heated in a furnace, the color is dark red, orange, gradually, you know why? As the iron bar heats up and the temperature rises, whats the maximum radiation energy? Do you know why? As the iron bar heats up, does the temperature rise? (with an iron heating temperature wavelength shift to short wavelength direction experienced far infrared, near infrared to visible light region) wavelength moves to short wave, which has experienced far infrared, near infrared to visible light region) 4 of the color of the sea is always why blue? This is caused by the non gray nature of the sea water. Why is the color of the water always blue? This is caused by the non gray nature of sea water. Is it always blue? (this is caused by the non gray property of seawater seawater visible light of d
